perf expr: Merge find_ids and regular parsing

Add a new option to parsing that the set of IDs being used should be
computed, this means every action needs to handle the compute_ids and
regular case. This means actions yield a new ids type is a set of ids or
the value being computed. Use the compute_ids case to replace find IDs
parsing.
