This should expose more of the actually used VALU instructions to the machine optimization passes. This also should help getting i1 handling into a better state. For not entirly understood reasons, this fixes the split-scalar-i64-add.ll test where a 64-bit add would only partially be moved to the VALU resulting in use of undefined VCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222256 91177308-0d34-0410-b5e6-96231b3b80d8
