Sanjay Patel 2f183e0a89 [x86, BMI] add TLI hook for 'andn' and use it to simplify comparisons ... For the sake of minimalism, this patch is x86 only, but I think that at least PPC, ARM, AArch64, and Sparc probably want to do this too. We might want to generalize the hook and pattern recognition for a target like PPC that has a full assortment of negated logic ops (orc, nand). Note that http://reviews.llvm.org/D18842 will cause this transform to trigger more often.
