An incremental parsing system for programming tools

As the call to `symbol_is_used` does not depend
on the production, it is more efficient to call it
only once outside the loop over productions.
I'm not sure if `rustc` is able to do this optimization
on its own (it would need to know that the function
is pure, which sounds difficult in general).

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
