Chris Lattner e30173ac33 Replace the PointerLikeTypeTraits::getNumLowBitsAvailable ... 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67979 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-29 04:32:37 +00:00
