Enable -fsanitize-address-use-after-scope only if -fsanitize=address is enabled
2016-12-08 Dmitry Vyukov <dvyukov@google.com>
* opts.c (finish_options): Enable
-fsanitize-address-use-after-scope only if -fsanitize=address is enabled
(not -fsanitize=kernel-address).
* doc/invoke.texi (-fsanitize=kernel-address):
Don't say that it enables -fsanitize-address-use-after-scope.
