The CopyToReg nodes will sometimes try to copy a value from a VGPR to an SGPR. This kind of copy is not possible, so we need to detect VGPR->SGPR copies and do something else. The current strategy is to replace these copies with VGPR->VGPR copies and hope that all the users of CopyToReg can accept VGPRs as arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183132 91177308-0d34-0410-b5e6-96231b3b80d8
