On my first attempt to rename & move the corresponding `Generation` enum into `lib/Target/AMDGPU/Utils/AMDGPUBaseInfo.h` I would need to adapt (at least) ~ 25 other files within the backend; and TBH I've yet to get it to work as expected.

Q: How should I go about this change to avoid introducing (lingering?) errors into the backend? Any suggestions welcome!
(Is there a way to narrow that number? [I guess not.])
