AMDGPU: Optimize amdgpu-no-* attributes

[arsenm]

Summary

This allows clobbering a few extra registers in the fixed ABI, and
avoids some workitem ID packing instructions.

[jdoerfert]

Not qualified to look at the ISel and other AMDGPU parts, one comment though.

Can we merge inputregs and impliciAttrNames into one array of structs so there is a proper one to one mapping, this is very implicit and harder to understand.

[arsenm]

Use pair between enum and string
