Rather than re-parsing and re-resolving the import path string, use
the PkgName object provided by types2 to determine what package path
it refers to.
Also, decompose importfile into smaller functions, so that we can
directly pass the already-resolved package path to the importer.
Finally, switch to simply using height as calculated by types2 rather
than redoing the calculations.

This CL refactors mkinlcall by extracting the core InlinedCallExpr
construction code into a new "oldInline" function, and adds a new
"NewInline" hook point that can be overriden with a new inliner
implementation that only needs to worry about the details of
constructing the InlinedCallExpr.
It also moves the delayretvars optimization check into CanInline, so
it's performed just once per inlinable function rather than once for
each inlined call.
Finally, it skips printing the function body about to be inlined (and
updates the couple of regress tests that expected this output). We
already report the inline body as it was saved, and this diagnostic is
only applicable to the current inliner, which clones existing function
body instances. In the unified IR inliner, we'll directly construct
inline bodies from the serialized representation.

During DWARF debug location generation, as a preamble to the main data
flow analysis, examine the function entry block to look for in-params
arriving in registers that are partially or completely dead, and
insert new OpArg{Int,Float}Reg values for the dead or partially-dead
pieces. In addition, add entries to the f.NamedValues table for
incoming live register-resident params that don't already have
entries. This helps create better/saner DWARF location expressions for
params. Example:
func foo(s string, used int, notused int) int {
return len(s) + used
}
When optimization is complete for this function, the parameter
"notused" is completely dead, meaning that there is no entry for it in
the f.NamedValues table (which then means we don't emit a DWARF
variable location expression for it in the function enty block). In
addition, since only the length field of "s" is used, there is no
DWARF location expression for the other component of "s", leading to
degraded DWARF.
There are still problems/issues with DWARF location generation, but
this does improve things with respect to being able to print the
values of incoming parameters when stopped in the debugger at the
entry point of a function (when optimization is enabled).

AutoTemp flag. This is necessary so that temporary variables

2. When sorting variables for stack frame layout, use a stable

This CL updates noder and typecheck to avoid a couple of instances of
redundant evaluation of type expressions:
1. When noding struct fields or parameter tuples, check for
syntax.Type reuse between adjacent fields and then reuse the
corresponding ir.Node type expression. It would perhaps be even better
to avoid re-noding the type expression too, but noder's days are
numbered anyway, so I'd rather be minimally invasive here.
2. When importing an empty interface, reuse the same cached empty
interface instance that is used for empty interfaces that appear in
source. This matches types2's behavior, which uses a single
types2.Interface instance for all empty interfaces.
These changes are motivated by making it possible to migrate from
typecheck to types2 while passing toolstash -cmp.

Since the number of files in the EOCD record isn't validated, it isn't
safe to preallocate Reader.Files using that field. A malformed archive
can indicate it contains up to 1 << 128 - 1 files. We can still safely
preallocate the slice by checking if the specified number of files in
the archive is reasonable, given the size of the archive.
Thanks to the OSS-Fuzz project for discovering this issue and to
Emmanuel Odeke for reporting it.

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.
