0b1d70db34 Always resolve ambiguities immediately
No more ambiguity nodes.
Also, when merging parse stacks, merge their successors if needed.

c1565c1aae Track AST nodes' sizes in characters as well as bytes
The `pos` and `size` functions for Nodes now return TSLength structs,
which contain lengths in both characters and bytes. This is important
for knowing the number of unicode characters in a Node.

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.

3430a5edcc Clarify distinction btwn tree padding, tree offset, node position
- Node position is public. It represents the node's first character
  index in the document.
- Tree offset is private. It represents the distance between the tree's
  first character index and it's parent's first character index.
- Tree padding is private. It represents the amount of whitespace
  (or other separator characters) immediately preceding the tree.

fbe8b0a905 Fix incremental parsing
Stop collapsing hidden symbols upon reducing them.
Sadly, this messes up the ability to re-use parse
trees. Instead, for now, hide these nodes when
stringifying parse trees
