[PATCH] D145343: [AMDGPU] Emit predefined macro `__AMDGCN_CUMODE_OPTION`

[Matt Arsenault via Phabricator via cfe-commits]

arsenm added a comment.

I think exposing whether or not the flag was used is weird/broken, as is including _OPTION in the name. Should just define to whether it's enabled or not
