[SCEV] Introduce bulk umin creation utilities
Add new umin creation method which accepts a list of operands.
SCEV does not represents umin which is required in getExact, so
it transforms umin to umax with not. As a result the transformation of
tree of max to max with several operands does not work.
We just use the new introduced method for creation umin from several operands.
