checksat :: SBool -> Query CheckSatResult

checkBranch :: SBool -> SBool -> Bool -> Query BranchCondition

Checks which branches are satisfiable, checking the pathconditions for consistency if the third argument is true. When in debug mode, we do not want to be able to navigate to dead paths, but for normal execution paths with inconsistent pathconditions will be pruned anyway.
