Simplify REG_SEQUENCE lowering. The TwoAddressInstructionPass takes the machine code out of SSA form by expanding REG_SEQUENCE instructions into copies. It is no longer necessary to rewrite the registers used by a REG_SEQUENCE instruction because the new coalescer algorithm can do it now. REG_SEQUENCE is just converted to a sequence of sub-register copies now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169067 91177308-0d34-0410-b5e6-96231b3b80d8
