Fix pr4843: When an instruction has multiple destination registers that are tied to different source registers, the TwoAddressInstructionPass needs to be smarter. Change it to check before replacing a source register whether that source register is tied to a different destination register, and if so, defer handling it until a subsequent iteration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80654 91177308-0d34-0410-b5e6-96231b3b80d8
