Fix PR4986. "r1024 = insert_subreg r1024, undef, 2" cannot be turned in an implicit_def. Instead, it's an identity copy so it should be eliminated. Also make sure to update livevariable kill information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82436 91177308-0d34-0410-b5e6-96231b3b80d8
