This branch had diverged considerably, so merging it required changing a lot
of code.

52daffb3f3 Separate syntax rules into flat lists of symbols
This way, every ParseItem can be associated with a particular production
for its non-terminal. That lets us keep track of which productions are
involved in shift/reduce conflicts.

ed11ef557a Fix expansion of repeat rules into recursive rules
Previously, the way repeat rules were expanded, the auxiliary
rule always needed to be reduced, even if the repeating content
was empty. This caused problems in parse states where some items
contained the repeat rule and some did not. To make those cases
work, the repeat rule had to explicitly be marked as optional.
With this change, that is no longer necessary.

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.
