Added ability to set a "cvc4-specific logic" in standards-compliant
SMT-LIBv1 and SMT-LIBv2 input:
In SMT-LIBv1, you specify the "cvc4_logic" benchmark attribute; for instance:
(benchmark actually_a_sat_benchmark_but_looks_like_uf
:logic QF_UF
:cvc4_logic { QF_SAT }
[...]
In SMT-LIBv2, you use a set-info; for instance:
(set-logic QF_UF)
(set-info :cvc4-logic "QF_SAT")
[...]
Right now, the only thing this does is disable the symmetry breaker for
benchmarks like the above ones.
As part of this work, TheoryEngine::setLogic() was removed (the logic field there
wasn't actually used anywhere, its need disappeared when
Theory::setUninterpretedSortOwner() was provided).
Also, Theory::d_uninterpretedSortOwner got a name change to
Theory::s_uninterpretedSortOwner, to highlight that it is static to the Theory
class. This represents a breakage of our separation goals for CVC4, since it
means that two SmtEngines cannot be created separately to solve a QF_AX and
QF_UF problem. A bug report is pending.
