This updates all regressions that pass check-unsat-cores to enable check-unsat-cores. This includes any incremental benchmark, which was disabled in run_regression.py previously.
It adds --no-check-unsat-cores to a few corner benchmarks that were previously disabled based on --incremental.
It also reverts a change to when proofs are disabled: options like sygus-inference should not permit proofs (or unsat cores).

This commit removes parser and printer support for old SMT-LIB standards and also converts all regression tests to 2.6.

This PR adds a simple BV solver that sends bit-blasting lemmas to the internal MiniSat.

This commit adds a check to make sure that the result of a `(check-sat)`
call matches the expected result set via `(set-info :status ...)`. In
doing so, it also fixes an issue where CVC4 would crash if asked for the
unsat core after setting the status to `unsat` but before calling
`(check-sat)` (see regression for concrete example). This happened
because CVC4 was storing the expected result and the computed result
both in the same variable (the expected result wasn't really being used
though). This commit keeps track of the expected result and the computed
result in separate variables to fix that issue.

* Enable BV proofs when using and eager bitblaster
Specifically:
* Removed assertions that blocked them.
* Made sure that only bitvectors were stored in the BV const let-map
* Prevented true/false from being bit-blasted by the eager bitblaster
Also:
* uncommented "no-check-proofs" from relevant tests
* Option handler logic for BV proofs
BV eager proofs only work when minisat is the sat solver being used by
the BV theory.
Added logic to the --proof hanlder to verify this or throw an option
exception.
* Bugfix for proof options handler
I forgot that proofEnabledBuild runs even if the --proof option is
negated. In my handler I now check that proofs are enabled.
* Clang-format
