would create illegal extract_subreg. e.g. vr1024 = extract_subreg vr1025, 1 ... vr1024 = mov8rr AH If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56118 91177308-0d34-0410-b5e6-96231b3b80d8
