Sanjay Patel 6357ccf57f [InstCombine] reassociate min/max intrinsics with constant operands ...

Integer min/max operations are associative:
  max (max X, C0), C1 --> max X, (max C0, C1) --> max X, NewC

https://alive2.llvm.org/ce/z/wW5HVM

This would avoid a regression when we canonicalize to min/max intrinsics
(see D98152 ).
