When performing a conditional branch depending on the value of a comparison %cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and with "false" under the false edge. This change enhances this to replace the negated compare (A!=B) with "false" under the true edge and "true" under the false edge. Reported to improve perlbench results by 1%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151517 91177308-0d34-0410-b5e6-96231b3b80d8
