Rewrite parser as recursive descent (#591)
* Remove Bison dependency
* Remove pre-generated parser files
* Rename build config from no-re2c-bison to no-re2c
* Add a simple make_unique implementation
* Move handling of module bindings into ir.cc
* Simplify lexer
- Remove lookahead, the parser handles this now
- Unify Token/LexerToken, it only contains terminal values now
- Refactor setting token type and value into one function (e.g.
LITERAL, RETURN => RETURN_LITERAL)
* New Parser
- Uses two tokens of lookahead (use Peek(0) or Peek(1))
- Consume() consumes one token of any kind
- Match(t) consumes the current token if it matches
- PeekMatch(t) returns true iff the token matches, but doesn't consume
- Basic error synchronization; plenty of room for improvement here
