Well, as all the other asan options are done as params, handling one option
differently is just too inconsistent.
The reason we went with params was that it was expected most users wouldn't
really need to play with the knobs, and we didn't want to be stuck in
supporting those forever (params aren't supported from one version to
another, can be replaced, removed, added etc.).
So, I think this really should be a param at this point and perhaps for GCC
6 we can discuss if we want to change the params into normal options.
