ff340f98e3 R600: Move DataLayout to AMDGPUTargetMachine 
This is a follow up to r227113.

It is now required to use the amdgcn target for SI and newer GPUs.

6e6318f148 Add target hook for whether it is profitable to reduce load widths 
Add an option to disable optimization to shrink truncated larger type
loads to smaller type loads. On SI this prevents using scalar load
instructions in some cases, since there are no scalar extloads.
