Sanjay Patel 536ffae2c4 [InstCombine] relax use constraint for min/max (~a, ~b) --> ~min/max(a, b) ...

In the minimal case, this won't remove instructions, but it still improves
uses of existing values.

In the motivating example from PR35834, it does remove instructions, and
sets that case up to be optimized by something like D41603:
