Additional assumption for solver to be used along with solver context,
but not used in core computation. This facility is useful when querying
for a core over only a subset of soft constraints. It has the same
logical functionality as asserting 'lit' to the solver and pushing a scope
(and popping the scope before the solver is used for other constraints).
