AMDGPU: Fix i64 global cmpxchg This was using extract_subreg sub0 to extract the low register of the result instead of sub0_sub1, producing an invalid copy. There doesn't seem to be a way to use the compound subreg indices in tablegen since those are generated, so manually select it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@272344 91177308-0d34-0410-b5e6-96231b3b80d8
