[PATCH, rs6000] pr65479 Add option to fix failing asan test cases.

This patch adds the -fasynchronous-unwind-tables option to several of the asan
test cases.  The option causes a full strack trace to be produced when the
sanitizer detects an error.  Without the full trace the 3 test cases fail.

Should we enable this whenever asan is used, instead?  Not just in the
testsuite?  And is this actually PowerPC-specific?

It is needed on these tests because of how they check the traceback stack looking for specific functions. Without the option only the first (triggering) function is included.

I don't know if the option is power specific but on x86 for instance the traceback gives all the functions without the option.
