function with a new NumLowBitsAvailable enum, which makes the value available as an integer constant expression. Add PointerLikeTypeTraits specializations for Instruction* and Use** since they are only guaranteed 4-byte aligned. Enhance PointerIntPair to know about (and enforce) the alignment specified by PointerLikeTypeTraits. This should allow things like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool> because the inner one knows that 2 low bits are free. llvm-svn: 67979
