There is precedence in InstCombine.

I could also envision CombinerHelperInteger, CombinerHelperPhi, ...
The motivation was for modularity and when the combiner grows, we can still use GitHub for git blame.
I also want to add combines for at least G_INSERT_VECTOR_ELT, G_INSERT_SUBVECTOR, G_EXTRACT_SUBVECTOR.
