1.go, 12.go: similar to calculating type sizes, we delay computing
instantiations during import until we get up to a top-level type, in
order to make sure recursive types are complete. But we should always
delay calculating sizes when we delay instantiating types, since
otherwise we may try to calculate the size of an incomplete type. So,
needed to add Defer/ResumeCheckSize in (*importReader).typ where we also
defer instantiations. (iimport.go)
2.go: when doing type substition, we have to handle named, parameterized
basic types i.e. the type has a type parameter even though the
underlying type is a basic type that doesn't depend on the parameter.
(subr.go)
3.go: for go 1.18, we allow arbitrary types in interfaces. We had
already allowed union types and tilde types, but didn't allow regular
non-interface types in Go 1.17 for compatibility. Just skip an error
in the case of 1.18. (size.go)
5.go: types2 and types1 differ in how they print out interfaces. types1
puts a space between "interface" and "{", types2 does not. So, since
some typenames come from types2 and some from types1, we need to remove
the space when printing out type arguments. (iimport.go/subr.go)
9.go: in subst.node(), we were missing the KeyExpr case where a node has
no type. The assertion is just there, to make sure we understand all the
cases where there is no type to translate. We could just remove the
whole error check. (stencil.go)
13.go: in subst.node(), missed handling the case where a method
expression is immediate called (which of course, is quite unusual, since
then there's no real reason to have used the method expression syntax in
that case). Just needed to add ir.OMETHEXPR in the OCALL switch
statement. (stencil.go)

The (*T).M method expression is where M is a value method, but the type

Setting `-gcflags=all=-d=unified` works for normal builds/tests, but
seems to have trouble with the test/run.go regress tests. So add a
GOEXPERIMENT knob to allow another way to turn on unified IR
construction, which plays better with all.bash.
While here, update two existing test expectations that currently fail
during GOEXPERIMENT=unified ./all.bash:
1. misc/cgo/errors/testdata/err2.go is testing column positions, and
types2 gets one case slightly better, and another case slightly
worse. For now, the test case is updated to accept both.
2. fixedbugs/issue42284.go is added to the list of known failures,
because it fails for unified IR. (It's an escape analysis test, and
escape analysis is working as expected; but unified is formatting an
imported constant value differently than the test's regexp expects.)

For typed vs un-typed operation, the compiler do the conversion
un-conditionally, so if the operation is invalid, the error report is
pointed to the conversion, instead of the invalid operation itself.
To fix this, only do the conversion when the operations are valid
for both types.

In a late change to golang.org/cl/320609, while going back and forth
on the meaning of the boolean result value for "checkFlags", I got one
of the cases wrong. As a result, rather than testing both default
flags and -G=3, we were (redundanly) testing default flags and -G=0.
I ran into this because in my local dev tree, I'm using types2 even
for -G=0, and evidently one of the recent types2 CLs changed the error
message in fixedbugs/issue10975.go. Fortunately, there haven't been
any other regressions despite lacking test coverage.
So this CL cleans things up a bit:
1. Fixes that test to use -lang=go1.17, so types2 reports the old
error message again.
2. Renames "checkFlags" to "validForGLevel" so the boolean result is
harder to get wrong.
3. Removes the blanket deny list of all -m tests, and instead adds the
specific tests that are still failing. This effectively extends -G=3
coverage to another 27 tests that were using -m but already passing,
so we can make sure they don't regress again.
4. Adds a -f flag to force running tests even if they're in the deny
list, to make it easier to test whether they're still failing without
having to edit run.go.

The build.Default context really needs to accurately describe
the default build context. The goexperiment tags being a special
case in the go command violates that rule and is the root cause
of the various try-bot failures blocking the enabling of regabi.
(The cleanups I made in golang.org/x/tools were long overdue
but are not strictly necessary for making regabi work; this CL is.)
Having moved the GOEXPERIMENT parsing into internal/buildcfg,
go/build can now use it to set up build.Default, in the new field
ToolTags, meant to hold toolchain-determined tags (for now,
just the experiments). And at the same time we can remove the
duplication of GOOS and GOARCH defaults.
And then once build.Default is set up accurately, the special case
code in cmd/go itself can be removed, and the special case code
in test/run.go is at least a bit less special.

Currently, run.go sets GOEXPERIMENT build tags based on the

the absolute experiment configuration. This differs from cmd/go. As a
result, if we set a baseline configuration and don't override it with
a GOEXPERIMENT setting, run.go won't set any GOEXPERIMENT build tags,
instead of setting the tags corresponding to the baseline
configuration.
Fix this by making compile -V=goexperiment produce the full
GOEXPERIMENT configuration, which run.go can then use to set exactly
the right set of build tags.

Adds code to the compiler's "order" phase to rewrite go and defer
statements to always be argument-less. E.g.
defer f(x,y) => x1, y1 := x, y
defer func() { f(x1, y1) }
This transformation is not beneficial on its own, but it helps
simplify runtime defer handling for the new register ABI (when
invoking deferred functions on the panic path, the runtime doesn't
need to manage the complexity of determining which args to pass in
register vs memory).
This feature is currently enabled by default if GOEXPERIMENT=regabi or
GOEXPERIMENT=regabidefer is in effect.
Included in this CL are some workarounds in the runtime to insure that
"go" statement targets in the runtime are argument-less already (since
wrapping them can potentially introduce heap-allocated closures, which
are currently not allowed). The expectation is that these workarounds
will be temporary, and can go away once we either A) change the rules
about heap-allocated closures, or B) implement some other scheme for
handling go statements.

Now that we can set GOEXPERIMENT at build time, we no longer need
-d=fieldtrack in the compiler to enabled field tracking at build time.
Switch the one test that uses -d=fieldtrack to use GOEXPERIMENT
instead so we can eliminate this debug flag and centralize on
GOEXPERIMENT.

This was a mostly clean merge, with the exception of codereview.cfg and
changes in src/go/types.
codereview.cfg for dev.typeparams is preserved in this CL. It should be
deleted before merging back to master.
The go/types changes were merged manually. For the most part this
involved taking the union of patches, with the following exceptions:
+ declInfo.aliasPos is removed, as it is not necessary in
dev.typeparams where we have access to the full TypeSpec.
+ Checker.overflow is updated to use the asBasic converter.
+ A TODO is added to errorcodes.go to ensure that go1.16 error codes
are preserved.

Currently, we call Warnl in SSA backend when we see a function
(defined or called) with regparams pragma. Calling Warnl in
concurrent environment is racy. As the debugging output is
temporary, for testing purposes we just pass -c=1. We'll remove
the pragma and the debugging print some time soon.

Factor out the existing "constant representation" check after
untyped constant arithmetic and combine with an overflow check.
Use a better heuristic for determining the error position if we
know the error is for a constant operand that is the result of an
arithmetic expression.
Related cleanups.
With this change, untyped constant arithmetic reports an error
when (integer) constants become too large (> 2048 bits). Before,
such arithmetic was only limited by space and time.

dot-imported objects to the package they were dot-imported through
(we call the map "dotImportMap").
3) From cmd/compile, borrow the "pkgnotused" function

As with CL 285875, this required resolving some conflicts around
handling of //go:embed directives. Still further work is needed to
reject uses of //go:embed in files that don't import "embed", so this
is left as a TODO. (When this code was written for dev.typeparams, we
were still leaning towards not requiring the "embed" import.)
Also, the recent support for inlining closures (CL 283112) interacts
poorly with -G=3 mode. There are some known issues with this code
already (#43818), so for now this CL disables inlining of closures
when in -G=3 mode with a TODO to revisit this once closure inlining is
working fully.

This merge had two conflicts to resolve:
1. The embed code on master had somewhat substantially diverged, so
this CL tediously backported the changes to dev.regabi. In particular,
I went through all of the embed changes to gc/{embed,noder,syntax}.go
and made sure the analogous code on dev.regabi in noder/noder.go and
staticdata/embed.go mirrors it.
2. The init-cycle reporting code on master was extended slightly to
track already visited declarations to avoid exponential behavior. The
same fix is applied on dev.regabi, just using ir.NameSet instead of
map[ir.Node]bool.
Conflicts:

The types2.Config.IgnoreBranches flag mistakenly excluded a
set of label-unrelated branch checks. After fixing this and
also adjusting some error messages to match the existing
compiler errors, more errorcheck tests pass now with the -G
option.
Renamed IngnoreBranches to IgnoreLabels since its controlling
label checks, not all branch statement (such as continue, etc)
checks.

This only works for functions; if you try it with a method, it will
fail. It does work for both local package and imports. For now,
it tells you when it thinks it sees either a declaration or a call of
such a function (this will normally be silent since no existing
code uses this pragma).
Note: it appears to be really darn hard to figure out if this
pragma was set for a method, and the method's call site. Better
ir.Node wranglers than I might be able to make headway, but it
seemed unnecessary for this experiment.

The files below had conflicts that required manual resolution.
The unresolved conflict in noder.go was just in the import
declaration (trivial). All the other conflicts are in tests
where the ERROR regex patterns changed to accomodate gccgo
error messages (incoming from dev.regabi), and to accomodate
types2 in dev.typeparams. They were resolved by accepting the
dev.regabi changes (so as not to lose them) and then by re-
applying whatever changes needed to make them pass with types2.
Finally, the new test mainsig.go was excluded from run.go when
using types2 due to issue #43308.

Change the run.go driver to recognize the "gc" build tag.
Change existing tests to use the "gc" build tag if they use some
feature that seems specific to the gc compiler, such as passing specific
options to or expecting specific behavior from "go tool compile".
Change tests to use the "!gccgo" build tag if they use "go build" or
"go run", as while those might work with compilers other than gc, they
won't work with the way that gccgo runs its testsuite (which happens
independently of the go command).

When functions are inlined, for instructions in the inlined body, does
-S print the location of the call, or the location of the body? Right
now, we do the former. I'd like to do the latter by default, it makes
much more sense when reading disassembly. With mid-stack inlining
enabled in more cases, this quandry will come up more often.
The original behavior is still available with -S=2. Some tests
use this mode (so they can find assembly generated by a particular
source line).
