[release-branch.go1.16] runtime/pprof: skip tests for AIX

Most of the time, the pprof tests are passing, except
for the builder. The reason is still unknown but I'd rather release
the builder to avoid missing other more important bugs.

Updates #45170

[release-branch.go1.16] syscall: syscall.AllThreadsSyscall signal handling fixes

The runtime support for syscall.AllThreadsSyscall() functions had
some corner case deadlock issues when signal handling was in use.
This was observed in at least 3 build test failures on ppc64 and
amd64 architecture CGO_ENABLED=0 builds over the last few months.

The fixes involve more controlled handling of signals while the
AllThreads mechanism is being executed. Further details are
discussed in bug #44193.

The all-threads syscall support is new in go1.16, so earlier
releases are not affected by this bug.

Fixes #45307

[release-branch.go1.16] cmd/compile: fix ANDI/SRWI merge on ppc64

The shift amount should be masked to avoid rotation values
beyond the numer of bits. In this case, if the shift amount
is 0, it should rotate 0, not 32.

Fixes #45636

[release-branch.go1.16] runtime: non-strict InlTreeIndex lookup in expandFinalInlineFrame

This is a follow-up to golang.org/cl/301369, which made the same change
in Frames.Next. The same logic applies here: a profile stack may have
been truncated at an invalid PC provided by cgoTraceback.
expandFinalInlineFrame will then try to lookup the inline tree and
crash.

The same fix applies as well: upon encountering a bad PC, simply leave
it as-is and move on.

For #44971
For #45480
Fixes #45482
