Philip Reames 675418ebc0 Extend known bits to understand @llvm.bswap ... This is a cleaned up patch from the one written by John Regehr based on the findings of the Souper superoptimizer. When writing tests, I was surprised to find that instsimplify apparently doesn't know how to collapse bit test sequences based purely on known bits. This required me to split my tests across both instsimplify and instcombine. Differential Revision: http://reviews.llvm.org/D13250 llvm-svn: 249453		2015-10-06 20:20:45 +00:00
