Ok, I've fallen ill and then completely forgot about this. Here's an
updated version.

I'm doing this below depending on whether CLANG is really clang or gcc.

I've kept the detect_leaks=0 because as kcc mentioned lots of tests
have leaks. If you desperately want this cluttered stderr you can
remove the detect_leaks=0 part from final patch (or I can do it
myself).

Fixed. This now allows user to override default script's ASAN_OPTIONS.
@Evgeniy: you can just remove detect_leaks=0 if you desperately want
this stderr clutter in runner's output.
