Changeset 90320ac for src/Parser/parserutility.h

Clean-up in the Pass template around call_accept. Removed overloads that no longer contain unique behaviour. Redundent early exits have been removed. Updated the names and removed redundent checks following up the result* type update. New constructors for the delta helper type show how the data is actually used. The differs functions are unused (that value is stored in the result* types).
