Enhance bool simplifcation in X86 to handle more cases This patch is revised based on patch from Victor Umansky <victor.umansky@intel.com>. More cases are handled in X86's bool simplification, i.e. - SETCC_CARRY - value is truncated to i1 with AND As a by-product, PR5443 is also fixed. llvm-svn: 179265
