Fix synthesized expressions being non-minimal

Let's try this again. The implementation of canRaise callback was
overly complicated and was causing the minimizer to ocassionally

Refactor bool exp synthesizer
...
It's now more intelligent about generating IS NULL clauses. For example,
instead of 'LOWER(param) IS NULL' it now generates 'param IS NULL'.

This also modifies the behavior of AND/OR operators to strictly return
true/false/null whereas previously they could return the value of the
first truthy/false operand. The purpose of this change is to maintain
expression equivalency before and after minimization.
