  Log Message:
  -----------
  [ConstraintElim] Move logic to get constraint for solving to helper.

Move common logic shared by callers of getConstraint that use the result
to query the constraint system to a new helper getConstraintForSolving.

This includes common legality checks (i.e. not an equality constraint,
no new variables) and the logic to query the unsigned system if possible
for signed predicates.
