e85f9d33c4 add "legacy" support for theory case splits
this replicates what was done in theory_str to add axioms excluding each
pair of literals from being assigned True at the same time;
no new heuristics are being used in smt_context (yet)

Murphy Berzish
e9411e5b8c explicitly re-introduce string axioms on refreshed string theory vars
this fixes at least one case (kaluza/unsat/big/9650.smt2) where a string
could have a negative length value due to a constraint that went out of scope
