R600: Add support for LDS atomic subtract Signed-off-by: Aaron Watry <awatry@gmail.com> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190200 91177308-0d34-0410-b5e6-96231b3b80d8

R600/SI: Use -verify-machineinstrs for most tests We can't enable the verifier for tests with SI_IF and SI_ELSE, because these instructions are always followed by a COPY which copies their result to the next basic block. This violates the machine verifier's rule that non-terminators can not folow terminators.

R600/SI: Don't display the GDS bit. It isn't actually used now, and probably never will be, plus it makes tests less annoying. I also think SC prints GDS instructions as a separate instruction name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204270 91177308-0d34-0410-b5e6-96231b3b80d8
