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.

git-svn-id: https://llvm.org/svn/llvm-project/libclc/trunk@260777 91177308-0d34-0410-b5e6-96231b3b80d8
