e3862cdc93 AMDGPU: Use rcp for fdiv 1, x with fpmath metadata 
Using rcp should be OK for safe math usually, so this
should not be replacing the original fdiv.

bef34e21c7 AMDGPU: Rename intrinsics to use amdgcn prefix 
The intrinsic target prefix should match the target name
as it appears in the triple.

This is not yet complete, but gets most of the important ones.
llvm.AMDGPU.* intrinsics used by mesa and libclc are still handled
for compatability for now.
