(backport from trunk to gcc 6)
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?
It already is on trunk... You mean the branches :-) It is okay for all
open release branches (i.e., 5 and 6). Or does it not apply to GCC 5?
Thanks,

Yes, I meant the 6 branch. I only tried it on 6 but it should be fine
for 5 too.
