Treat parse conflicts as errors in grammar compilation

For now, only reduce/reduce conflicts w/ no tie-breaking precedence
are treated as errors. The rest are dropped, because shift/reduce
conflicts are currently very common because we don't have a way
of specifying associativity along w/ precedence.

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.

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.
