New Revision: 155288

URL: http://llvm.org/viewvc/llvm-project?rev=155288&view=rev
Log:
Remove unused PointerLikeTypeTraits for IndexListEntry.

It set NumLowBitAvailable = 3 which may not be true on all platforms.  We only
ever use 2 bits (the default) so this assumption can be safely removed

Should fix PR12612.
