Subject: Remove unused PointerLikeTypeTraits for IndexListEntry.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=0b5ad0b9d902620b81268add3f554d73a6d92fc1;p=oota-llvm.git

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.
