e16f64c094 misc: log 'ok' from 'go run' tests on success 
Otherwise, these tests produce no output, which can make the overall
output of all.bash a bit tricky to decipher.

Updates #30316
Updates #29062

d1383b5b8f misc/cgo/testsigfwd: add missing return statement 
Fixes C compiler warning:

./main.go:54:1: warning: control reaches end of non-void function [-Wreturn-type]

Should help fix the linux builders
that broke due to CL 23005.

fbdfa99246 runtime: for c-archive/c-shared, don't install unnecessary signal handlers 
Only install signal handlers for synchronous signals that become
run-time panics.  Set the SA_ONSTACK flag for other signal handlers as
needed.

Fixes #13028.
Update #12465.
Update #13034.
Update #13042.

5c8fbc6f1e runtime: signal forwarding 
Forward signals to signal handlers installed before Go installs its own,
under certain circumstances.  In particular, as iant@ suggests, signals are
forwarded iff:
   (1) a non-SIG_DFL signal handler existed before Go, and
   (2) signal is synchronous (i.e., one of SIGSEGV, SIGBUS, SIGFPE), and
   	(3a) signal occured on a non-Go thread, or
   	(3b) signal occurred on a Go thread but in CGo code.

Supported only on Linux, for now.
