parser: cleanup and rework optimization and dump flag handling

In preparation for more flags (not all of the backend dfa based),
rework the optimization and dump flag handling which has been exclusively
around the dfa up to this point.

- split dfa control and dump flags into separate fields. This gives more
  room for new flags in the existing DFA set
- rename DFA_DUMP, and DFA_CONTROL to CONTROL_DFA and DUMP_DFA as
  this will provide more uniform naming for none dfa flags
- group dump and control flags into a structure so they can be passed
  together.
