This does some improvements/cleanup to the recently introduced scavengeRegisterBackwards() functionality: - Rewrite findSurvivorBackwards algorithm to use the existing LiveRegUnit::accumulateBackward() code. This also avoids the Available and Candidates bitset and just need 1 LiveRegUnit instance (= 1 bitset). - Pick registers in allocation order instead of register number order. llvm-svn: 305817
