Unsure:
- RULE_INVALID_SET
- TOKEN_ALIAS_CONFLICT (In combined only. Need to compare tokens def in combined with lexer rule in implicit lexer)
- IMPORTED_TOKENS_RULE_EMPTY(arg,arg2) ::= "no lexer rules contributed to <arg> from imported grammar <arg2>" This is for unreachable alts when dfa is Tokens rule. This is more of an LL
decision thing.
