2ee5dbb79b56539b580c3a36eec5a025d08b7022 by Eric Fiselier <ericwf@google.com>:

Unconditionally apply no-sanitize attributes.

We currently fail to apply the attributes in open-source
land because the build system doesn't define ADDRESS_SANITIZER
like we expect.

The attributes should have no effect when the sanitizers are
disabled.
