It's not trivial to make a comprehensive check
due to inferior pointers, reflect, gob, etc.
But this is essentially what I've used to debug
the GC issues.
Update #5193.

Apologies for not reviewing the previous CL; I was on the road.
The text was misleading; execution is no more separate than with
any other test. Rewritten. Dropped the odd adverb.

The spec doesn't explicitly say that trailing data is okay, but a lot
of people do this and most unzippers will handle it just fine. In any
case, this makes the package more useful, and led me to make the
directory parsing code marginally more robust.
Fixes#5228.

Use atomic operations on flags field to make sure we aren't
losing a flag update during parallel map operations.

It changes an exported API, and breaks the build.

Don't measure wall time in map.go. Keep it portable
and only test NaN, but not time.
Move time tests to mapnan.go and only measure user CPU time,
not wall time. It builds on Darwin and Linux, the primary
platforms where people hack on the runtime & in particular
maps. The runtime is shared, though, so we don't need it to
run on all of the platforms.
Fixes flaky build failures like:

Before, an empty TMPDIR would lead to:
cannot create <nil>/go.o: No such file or directory

The invariant is that there must be at least one running P or a thread polling network.
It was broken.

This makes it an unsafe.Pointer in Go so the garbage collector
will treat it as a pointer to untyped data, not a pointer to
bytes.

If for whatever reason seh points into Go heap region,
the dangling pointer will cause memory corruption during GC.

The offset of an embedded field s.X must be relative to s
and not to the implicit s.Field of which X is a direct field.
Moreover, no indirections may happen on the path.

We've decided to leave logging to third-parties (there are too
many formats), which others have done.
And we can't change the behavior of the various response
fields at this point anyway. Plus I argue they're correct and
match their documention.

The compilers used to generate only one 'm' symbol
to record the stack frame size for each function.
In cmd/nm, the 'm' and 'f' symbols are handled in
the same switch case with a special exception for
the symbol described above called ".frame".
Now that the compilers emit additional 'm' symbols
for precise garbage collection of the stack, the
current logic is incorrect. cmd/nm will attempt to
interpret these new 'm' symbols as 'f' symbols and
add them to the file name index table.
This fails with an out-of-memory condition when
zenter encounters an 'm' symbol with a very large
value (usually the .args symbol indicating a
variadic NOSPLIT function).
