All feedback from the earlier version has been taken into account now. This patch adds the -fasynchronous-unwind-tables option to compilations when the -fsanitize=address option is seen but not if any -fasynchronous-unwind-tables options were already specified. -fasynchronous-unwind-tables causes a full strack trace to be produced when the sanitizer detects an error. Without the full trace several of the asan test cases fail on powerpc. 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?
