Fix machine-cp by having it to check sub-register indicies. e.g.
ecx = mov eax al = mov ch The second copy is not a nop because the sub-indices of ecx,ch is not the same of that of eax/al. Re-enabled machine-cp. PR11940 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151002 91177308-0d34-0410-b5e6-96231b3b80d8
