[llvm] AMDGPU/GlobalISel: Uniformity info based regbankselect (PR #73684)

[Pierre van Houtryve via llvm-commits]

https://github.com/Pierre-vh requested changes to this pull request.

extra small nit: Title should use `[AMDGPU][GlobalISel]` just to make git log easier to search

Also description is a bit confusing, do you intend to add all the opcodes in this commit if the direction is good to go?
Or will this only implement G_FADD and others will come in other patches?
In any case please update the description to reflect the intention
