Represent byte, char and tree counts as 32 bit numbers
...
The parser spends the majority of its time allocating and freeing trees and stack nodes.
Also, the memory footprint of the AST is a significant concern when using tree-sitter
with large files. This library is already unlikely to work very well with source files
larger than 4GB, so representing rows, columns, byte lengths and child indices as
unsigned 32 bit integers seems like the right choice.

Reuse nodes based on state matching, not sentential form validity
...
I think that state matching is the only correct strategy for incremental
node reuse that is compatible with the new error recovery algorithm. It's
also simpler than the sentential-form algorithm. With the compressed parse
tables, state matching shouldn't be too conservative of a test.
