  [LoopPeel] Support min/max intrinsics in loop peeling (#93162)

This patch adds processing of min/max intrinsics in LoopPeel in the
similar way as it was done for conditional statements: for
min/max(IterVal, BoundVal) we peel iterations where IterVal < BoundVal
for monotonically increasing IterVal; for monotonically decreasing
IterVal we peel iterations where IterVal > BoundVal (strict comparision
predicates are used to minimize number of peeled iterations).
