<pre>Currently Address Sanitizer sets __SANITIZE_ADDRESS__ preprocessor flag. I
think will be good idea to do this for other sanitizers for consistency,
particularly for Undefined Behavior Sanitizer.
Background: I got -Wdisabled-optimization warnings when compiled my project
with Undefined Behavior Sanitizer with GCC 5.4. I'd like to suppress warnings
in individual file with #pragma only for Undefined Behavior Sanitizer
instrumentation.</pre>
