TwoAddressInstructionPass enhancement. After it converts a two address instruction into a 3-address one, sink it past the instruction that kills the read-mod-write register if its definition is used past the kill. This reduces the number of live register by one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48333 91177308-0d34-0410-b5e6-96231b3b80d8
