In lexer, prefer tokens to skipped separator characters
...
This was causing newlines in go and javascript to be parsed as
meaningless separator characters instead of statement terminators

Remove magic number from generated symbols enums
...
The symbol numbers 0 and 1 are reserved for 'error' and 'eof',
so the grammar's start symbol is always 2.

Separate functions for building parse and lex tables
...
Now, instead of adding states to the lex table as they are needed
by the parse states, we iterate over the parse states after the fact
and set up their corresponding lex states. This has the nice side
effect that the lex states are in a more readable order.

Fix handling of tokens consisting of separator characters

such as newlines, whose characters overlap with the separator
characters, can now be correctly recognized.
