When plugin is used, we already mark all exported methods
reachable. However, when the plugin and the host program share
a common package, an unexported method could also be reachable
from both the plugin and the host via interfaces. We need to mark
them as well.

When ASan is enabled, treat conversions to unsafe.Pointer as
an escaping operation. In this way, all pointer operations on
the stack objects will become operations on the escaped heap
objects. As we've already supported ASan detection of error
memory accesses to heap objects. With this trick, we can use
-asan option to report errors on bad stack operations.

go:embed disallows using symlinked files by design.
crypto/elliptic is the first std package to use it as of CL 380475,
and unfortunately that broke the TestRepeatBootstrap long test.
The reason it uses symlinks is for speed; it wants to copy GOROOT/src,
but regular files aren't going to be modified in any way,
so a symlink, if supported, means not needing to copy the contents.
Replace the symlink attempt with hard links,
which will mean regular files remain as such, fixing go:embed.
It's worth noting that on many systems hard links won't work,
as the temporary filesystem tends to be separate,
but it doesn't hurt to try.
In my system, where /tmp is tmpfs, the test now copies more bytes.
With the added Logf, I can see overlayDir goes from ~30ms to ~100ms.
This makes sense, as GOROOT/src currently weighs around 100MiB.
To alleviate that slow-down, stop copying testdata directories,
as they currently weigh around 20MiB and aren't needed for the test.
This gets overlayDir on my system down to an acceptable ~70ms.
I briefly considered teaching overlayDir what files can be symlinks,
but that seemed fairly complex long-term, as any file could be embedded.
While here, start using testing.T.TempDir and fs.WalkDir.

These tests use a slice to represent the base C compiler command (with
flags). Appending to that slice can cause subtle aliasing bugs, such
as commands that silently corrupt the arguments of other concurrent
commands in parallel tests.
In this change, we explicitly reduce the capacity of the command slice
to force appends to it to always allocate unique new slices.

The current -asan option does not print where the error occurred. The
reason is that the current implementation calls incorrect asan runtime
functions, which do not pass sp and pc where asan runtime functions are
called, and report the stack trace from the native code. But asan runtime
functions are called from cgo on a separated stack, so it cannot dump the
Go stack trace correctly.
The correct asan runtime function we should call is __asan_report_error,
which will pass sp and pc, and report where the error occurred correctly.
This patch fixes this issue.

Fixes for #49680, #49695, #45867, and #49370 all assumed that
SetGCPercent(-1) doesn't block until the GC's mark phase is done, but
it actually does. The cause of 3 of those 4 failures comes from the fact
that at the beginning of the sweep phase, the GC does try to preempt
every P once, and this may run concurrently with test code. In the
fourth case, the issue was likely that only *one* of the debug_test.go
tests was missing a call to SetGCPercent(-1). Just to be safe, leave a
TODO there for now to remove the extraneous runtime.GC calls, but leave

Consider the top-level test directory, testdata, and vendor directories
out of scope, since there are many files that don't follow strict gofmt
formatting, often for intentional and legitimate reasons (testing gofmt
itself, invalid Go programs that shouldn't crash the compiler, etc.).
That makes it easy and safe to gofmt -w the .go files that are found
with gofmt -l with aforementioned directories filtered out:
$ gofmt -l . 2>/dev/null | \
grep -v '^test/' | \
grep -v '/testdata/' | \
grep -v '/vendor/' | wc -l
51
None of the 51 files are generated. After this change, the same command
prints 0.
For #41184.

Conflicts:
- src/go/types/check_test.go
CL 324730 on dev.typeparams changed the directory paths in TestCheck,
TestExamples, and TestFixedbugs and renamed checkFiles to testFiles;
whereas CL 337529 on master added a new test case just above them and
that used checkFiles.

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.)
Updates #46786.

LLD won't import a .dll directly and instead requires an import library.
So generate these using -out-implib, the same way as was done in CL
312046, where it makes sense, and elsewhere build the import library
using a def file. We can't use -out-implib all the time, because the
output file gets overwritten each time the linker is called, rather than
merged.

Clang does not produce binaries with an .edata section, even when it
exports symbols properly, so just skip this binutils-specific test for
that case. Later we can rewrite these tests entirely to do something

The test was using the wrong column numbers, and was erroneously
passing because there happened to be line numbers that matched those
column numbers. Change the test harness to require the expected line
number for the ERROR HERE regexp case, so that this doesn't happen again.
Also rename a couple of variables in the test to avoid useless
redeclaration errors.
