Andrew G. Morgan 7e97e4e8cc 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 #44193
