[InstCombine] fold sub-of-umax to 0-usubsat
Op0 - umax(X, Op0) --> 0 - usub.sat(X, Op1)
I'm not sure if this is really an improvement in IR because

but this lines up with the fold we do for the icmp+select
idiom and removes another diff from D98152.
This is similar to the previous fold in the code that was
added with:
