[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.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65479 for more information. Bootstrapped and tested on powerpc64le-unknown-linux-gnu, powerpc64be-unknown-linux-gnu, and x86_64-pc-linux-gnu with no regressions. Is this ok for trunk?
