545e575508 Revert "Remove the separator characters construct" 
This reverts commit 5cd07648fd.

The separators construct is useful as an optimization. It turns out that
constructing a node for every chunk of whitespace in a document causes a
significant performance regression.

5cd07648fd Remove the separator characters construct 
Now, grammars can handle whitespace by making it another ubiquitous
token, like comments.

For now, this has the side effect of whitespace being included in the
tree that precedes it. This was already an issue for other ubiquitous
tokens though, so it needs to be fixed anyway.

e93e254518 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

1cc7e32e2d Fix handling of tokens consisting of separator characters 
The parser is no longer hard-coded to skip whitespace. Tokens
such as newlines, whose characters overlap with the separator
characters, can now be correctly recognized.
