Yakir Vizel 23a8e59493 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.

Arie Gurfinkel 9f0eb367b1 ground lemmas during propagation when qlemmas are disabled
When asserting quantified lemmas are disabled, ground a lemma
explicitly during propagate to make sure that it is ground using our
local set of skolem constants.
