[BasicAA] Cache nonEscapingLocalObjects for alias() calls.
Summary:
Use a small cache for Values tested by nonEscapingLocalObject().
Since the calls to PointerMayBeCaptured are fairly expensive, this saves
a good amount of compile time for anything relying heavily on
BasicAA.alias() calls.
This uses the same approach as the AliasCache, i.e. the cache is reset
after each alias() call. The cache is not used or updated by modRefInfo
calls since it's harder to know when to reset the cache.
Testcases that show improvements with this patch are too large to
include. Example compile time improvement: 7s to 6s.
