The `runAssignment` code path makes sure to check that the

so; this patch ensures that the check happens on every code path.

I chose not to change the `runAssignment` code path to use this new
executeParserAction function, since that whole spiel is going away.

Remove submodules now that parsers provide grammars themselves.

Codegen migration leftovers
