Jan Vesely 3d349ea98e Make image builtins r600/llvm-3.9 only 
The implementation uses r600 sepcific intrinsics
LLVM-4 switched to _ro_t and _rw_t image types
Portions of the code can be moved back as more targets/llvm versions add image support

Matt Arsenault a48e15c6cb Split sources for amdgcn and r600 
Most files remain in a common amdgpu directory.

Also switches barriers to to use convergent,
and use llvm.amdgcn.s.barrier.

This now requires 3.9/trunk to build amdgcn.
