When SimpleRegisterCoalescing is trimming kill flags on a physical register operand, also check if subregisters are killed. Add <imp-def> operands for subregisters that remain alive after a super register is killed. I don't have a testcase for this that reproduces on trunk. <rdar://problem/8441758> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116940 91177308-0d34-0410-b5e6-96231b3b80d8
