AMDGPU: Reduce number of copies emitted Instead of always inserting a copy in case the super register is itself a subregister, only extract to the super reg class if this is actually the case. This shouldn't really change codegen, but makes looking at the output of SIFixSGPRCopies easier to read. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@248467 91177308-0d34-0410-b5e6-96231b3b80d8
