This pass is only concerned with ZMM0-15 and YMM0-15. For YMM we use VR256 which only contains YMM0-15, but for ZMM we were using VR512 which contains ZMM0-31. Using VR512_0_15 is more correct. Given that the ABI and register allocator will use registers in order, its unlikely that register from 16-31 would be used without also using 0-15. So this probably doesn't functionally matter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@372933 91177308-0d34-0410-b5e6-96231b3b80d8
