Don't try to clear cache on garbage objects
Method cache can be cleared during lazy sweeping. An object that will
be collected during lazy sweep *should not* have it's method cache
cleared. Soon-to-be-collected objects can be in an inconsistent state and
this can lead to a crash. This patch just leaves early if the object is
going to be collected.
Fixes [Bug #17536]
