Lots of machine verifier errors result from using a plain GPR regclass for incoming argument copies. A more restrictive rGPR class is more appropriate since it more accurately represents what's happening, plus it lines up better with isel later on so the verifier is happier. Reduces the number of ARM fast-isel tests not running with the verifier enabled by over half. rdar://12594152 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188592 91177308-0d34-0410-b5e6-96231b3b80d8
