Properly clean up assertion stack in CnfProof (#2147)
Fixes issue #2137. CnfProof has a stack of assertions that are being
converted to clauses. Previously, it could happen that while an
assertion was being added, TheoryProxy::explainPropagation() would be
called from Solver::reason() and push an assertion to the stack that was
then not removed. This lead to a clause id of the assertion being
associated with the explanation instead, which in turn could lead to a
wrong unsat core. This commit identifies two cases where
TheoryProxy::explainPropagation() is called without cleaning up the
assertion stack afterwards. It also adds an assertion that the assertion
stack must be empty when we are getting the unsat core.

Check unsat cores in regressions also without LFSC (#1955)
When moving the LFSC checker out of the CVC4 repository in commit
dfa69ff98a14fcc0f2387e59a0c9994ef440e7d0, we disabled checking unsat
cores when CVC4 was compiled without LFSC due to the complexity of the
regression script. This commit changes the new(-ish) Python regression
script to check unsat cores even when CVC4 was compiled without LFSC.
This is done by having two separate flags, --with-lfsc and
--enable-proof, for the regression script that mirror the configuration
flags. The regression script performs unsat cores and proofs checks
based on those flags.
Additionally, this commit changes the regression script to check proofs
and unsat cores in two independent runs. Testing them in a single run

Workaround for incremental unsat cores (#1962)
This commit implements a workaround for computing unsat cores while
doing incremental solving to address #1349. Currently, our resolution
proofs do not handle clauses with a lower-than-assertion-level correctly
because the resolution proofs for them get removed when popping the
context but the SAT solver keeps using them. The workaround changes the
behavior of the SAT solver to add clauses always at the current level if
incremental solving and unsat cores are enabled. This makes sure that
all learned clauses are removed when we pop below the level that they
were learned at. This may degrade performance because the SAT solver has
to relearn clauses.
