First pass at adding support for `finally` clauses. I took a simple approach where we reify the JS semantics around return shadowing in the HIR and output. Ie, we create a temporary variable that will be the return value, and change returns in the try/catch to assign to that value and then break to the finalizer. In the finalizer returns work as normal, but we put a final extra "if temporary set, return it" statement. It would be more ideal to fully restore the return shadowing, but given that finally clauses are relatively rare this seems like a reasonable compromise. I need to do more analysis to make sure the approach is correct.

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
