[PATCH] D130096: [Clang][AMDGPU] Emit AMDGPU library control constants in clang

[Joseph Huber via Phabricator via cfe-commits]

Updating. I realized all of the math-related ones are already covered by driver options for AMDGPU passing the appropriate fp contract to the frontend. This patch gets rid of most of that handling and just uses those directly. Also makes it easier to test.

We also check if the `+wavefront64` feature was explicitly turned on as part of @yaxunl's suggestion.
