Extend the CoalescerPair interface to handle symmetric sub-register copies. Now both SrcReg and DstReg can be sub-registers of the final coalesced register. CoalescerPair::setRegisters still rejects such copies because RegisterCoalescer doesn't yet handle them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156848 91177308-0d34-0410-b5e6-96231b3b80d8
