Sanjoy Das 574e01c32e Teach ScalarEvolution to exploit min and max expressions when proving 
isKnownPredicate.

The motivation for this change is to optimize away checks in loops
like this:

    limit = min(t, len)
    for (i = 0 to limit)
      if (i >= len || i < 0) throw_array_of_of_bounds();
      a[i] = ...
