  Log Message:
  -----------
  [AMDGPU] Use MUBUF instructions for global address space access

Currently, the compiler crashes in instruction selection of global
load/stores in gfx600 due to the lack of FLAT instructions. This patch
fix the crash by selecting MUBUF instructions for global load/stores
in gfx600.
