…a failed constraint. As solveRec() already does, exit immediately if we have a failed constraint from constraint generation. Not doing so means that we can create a SolverScope in constraint propagation, and on destruction of that SolverScope we clear out the failedConstraint field, obscuring the fact that we had a failure.

…a failed constraint.
As solveRec() already does, exit immediately if we have a failed
constraint from constraint generation. Not doing so means that we can
create a SolverScope in constraint propagation, and on destruction of
that SolverScope we clear out the failedConstraint field, obscuring the
fact that we had a failure.
