The buildinfo used for a testmain is a copy from the buildinfo produced
for the package under test, and that in turn is only computed if the
package under test is package main. If there are //go:debug directives
in a test file for package main, the godebugs for the testmain (which
are computed using the regular package files as well as the test files'
//go:debug directives) will be different from those used to produce the
buildinfo of the package under test (computed using the //go:debug
directives only in the main package). In that case, recompute the
buildinfo for the testmain to incorporate the new godebug information.
Since we've only been generating buildinfo for tests on package main, in
this CL we'll only recompute the buildinfo if the test is for package
main. It's not clear to me though if we should be computing the
buildinfo for all test mains (or none of them?)

This CL adds a "deadlocals" pass, which runs after inlining and before
escape analysis, to prune any unneeded local variables and
assignments. In particular, this helps avoid unnecessary Addrtaken
markings from unreachable closures.
Deadlocals is sensitive to "_ = ..." as a signal of explicit
use for testing. This signal occurs only if the entire
left-hand-side is "_" targets; if it is
`_, ok := someInlinedFunc(args)`
then the first return value is eligible for dead code elimination.
Use this (`_ = x`) to fix tests broken by deadlocals elimination.
Includes a test, based on one of the tests that required modification.

Currently, the debuglog tests only run when the debuglog build tag is
set because, until the last few CLs, all of debuglog was compiled away
without that build tag. This causes two annoying problems:
1. The tests basically never run, because we don't regularly test this
configuration.
2. If you do turn on the debuglog build tag, it's probably because
you're adding debuglogs into the runtime, which are very likely to
mess up these tests, so you wind up disabling the tests and they,
again, don't get coverage.
Now we've set things up so the debuglog implementation is always
accessible, if you ask nicely enough. So we can switch these tests to
run when the tag is *not* set, and turn off when the tag *is* set (and
you're probably adding actual log statements).

Currently, the debuglog build tag controls the dlogEnabled const, and
all methods of dlogger first check this const and immediately return
if dlog is not enabled. With constant folding and inlining, this makes
the whole dlog implementation compile away if it's not enabled.
However, we want to be able to test debuglog even when the build tag
isn't set. For that to work, we need a different mechanism.
This CL changes this mechanism so the debuglog build tag instead
controls the type alias for dlogger to be either dloggerImpl or
dloggerFake. These two types have the same method set, but one is just
stubs. This way, the methods of dloggerImpl don't need to be
conditional dlogEnabled, which sets us up to use the now
fully-functional dloggerImpl type in the test.
I confirmed that this change has no effect on the final size of the
cmd/go binary. It does increase the size of the runtime.a file by 0.9%
and make the runtime take ever so slightly longer to compile because
the compiler can no longer simply eliminate the bodies of the all of
dlogger during early deadcode. However, this all gets eliminated by
the linker. I consider this worth it to always get build and test
coverage of debuglog.

The trace parser was using an otherwise-unused event argument to hold an
extra goroutine state argument for the GoStatus & GoStatusStack events.
This is needed because the execution tracer just records the "after" for
state transitions, but we want to have both the "before" and "after"
states available in the StateTransition info for the parsed event. When
GoStatusStack was added, the size of the argument array was increased to
still have room for the extra status. However, statuses are currently
only 1 byte, and the status argument is 8 bytes, so there is plenty of
room to pack the "before" and "after" statuses in a single argument. Do
that instead to avoid the need for an extra argument.

The relocation number of each architecture starts from 0. objabi.ElfRelocOffset
+ objabi.RelocType(xxx) cannot uniquely represent a relocation, so the new
argument 'arch' was added to help identify relocation.

1) Factor out handling of receiver from Checker.funcType into
Checker.collectRecv. Analyze the receiver parameter "manually"
without resorting to calling Checker.collectParams.
The code is more straight-forward and error handling is simpler
because constructing the receiver type and variable is all handled
in one function.
2) Change Checker.collectParams to collect parameter names and
corresponding parameter variables, but do not declare them.
Instead return two equal-length slices of parameter names
and variables for later declaration.
3) Streamline Checker.funcType into a sequence of simple steps.
By declaring the receiver and parameters after type parameters,
there is no need for a temporary scope and scope squashing anymore.
4) Simplify Checker.unpackRecv some more: don't strip multiple
*'s from receiver type expression because we don't typecheck
that expression as a whole later (we don't use collectParams
for receiver types anymore). If we have a **T receiver, we
need to use *T (one * stripped) as receiver base type expression
so that we can report an error later.
5) Remove Checker.recvTParamMap and associated machinery as it is
not needed anymore.
6) Remove Scope.Squash/squash as it is not needed anymore.
7) Remove the explicit scope parameter from Checker.collectParams
as it is not needed anymore.
8) Minor adjustments to tests: in some cases, error positions have
shifted slightly (because we don't use Checker.collectParams to
typecheck receivers anymore), and in some cases duplicate errors
don't appear anymore (resolves TODOs).
Fixes#51343.

Instead of returning the receiver type name (rname), return the
receiver type base expression (base), with pointer indirections
stripped. The type base may or may not not be a type name. This
is needed for further rewrites of the signature type-checking code.
Adjust call sites accordingly to preserve existing behavior.
For #51343.

When reporting an error for the element type of a struct literal, use
the element type's type name rather than it's underlying/core type.
Also, combine error reporting for invalid composite literal types in
one place, at the end.
