StackProtector: Use RuntimeLibcalls to query libcall names (#147913)
The compiler should not introduce calls to arbitrary strings
that aren't defined in RuntimeLibcalls. Previously OpenBSD was
disabling the default __stack_chk_fail, but there was no record
of the alternative __stack_smash_handler function it emits instead.

This also avoids a random triple check in the pass.
