This MI-level pass was necessary when VSX support was first being developed, specifically, before the ABI code had been updated to use VSX registers for arguments (the register assignments did not change, in a physical sense, but the VSX super-registers are now used). Unfortunately, I never went back and removed this pass after that was done. I believe this code is now effectively dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227767 91177308-0d34-0410-b5e6-96231b3b80d8
