Initial commit of QGen

Controlled by fixedpoint.spacer.use_quanti_generalizer

measure cumulative time, number of invocations, and number of failed
SMT calls

Relaxing equality in a pattern: if a variable equals a numeral, relax with GE

pob::get_skolems() returns all skolems that might appear in the pob.
New skolems must be added above the largest index in that map,
even if they are not used in the pob itself.

pattern generalization should be done before the pattern is skolemized and
added into the new cube.
