Before the patch we took advantage of the fact that the compare and branch are glued together in the selection DAG and fused them together (where possible) while emitting them. This seemed to work well in practice. However, fusing the compare so early makes it harder to remove redundant compares in cases where CC already has a suitable value. This patch therefore uses the peephole analyzeCompare/optimizeCompareInstr pair of functions instead. No behavioral change intended, but it paves the way for a later patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187116 91177308-0d34-0410-b5e6-96231b3b80d8
