Log Message:
Expunged 'OrCriterion' completely, as it caused a problem with implication
detection.  Specifically, the system couldn't detect that (a|x) implies
(b|y) if a implies b, and a is true at runtime.  However, if these cases
are split into separate predicates for a, x, b, and y, then when a and b
both apply the implication will be clear.  Unfortunately, this increases
the number of cases that have to be examined for such expressions.
