RFC: atomic operations on SI+
Hi Tom, Matt, I'm working on a project that needs few coherent atomic operations (HSA mode: load, store, compare-and-swap) for std::atomic_uint in HCC. the attached patch implements atomic compare and swap for SI+ (untested). I tried to stay within what was available, but there are few issues that I was unsure how to address: 1.) it currently uses v2i32 for both input and output. This

The current datalayout for r600 includes n32:64, which is odd
