Jan Vesely 04a46bf0a2 amdgcn,popcount: Workaround broken llvm.ctpop intrinsic on some GCN ASICs 
This is only really needed for VI+ ASICs. However, llvm would cast the value to
i32 for older asics anyway. The proper fix is in LLVM-7 (r326535).
Fixes CTS popcount on carrizo.

Jan Vesely 999b1d9426 amdgcn: rewrite barrier() using fence and clang __builtin_amdgcn_s_barrier 
Specs require using fences when barrier() is invoked:
"The barrier function will either flush any variables stored in local memory
or queue a memory fence to ensure correct ordering of memory operations to local memory."
and
"The barrier function will queue a memory fence to ensure correct ordering
of memory operations to global memory."

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.
