Aaron Watry 036303c4bf R600: Add cmpxchg instruction for evergreen
Refactored the R600_LDS_1A2D class a bit to get it to actually work.

It seemed to be previously unused and broken.

We also have to disable the conversion to the noret variant for now in
R600ISelLowering because the getLDSNoRetOp method only handles 1A1D LDS ops.

Someone can feel free to modify the AMDGPU::getLDSNoRetOp method to
work for more than 1A1D variants of LDS operations. It's being left as a
future TODO for now.

// XXX: Lowering SELECT_CC will sometimes generate fp_to_[su]int nodes,
// which do not need to be truncated since the fp values are 0.0f or 1.0f.
// We should look into handling these cases separately.
