We now do a single pass over the HIR, building up two data structures:
* One tracks values that are known macro tags or macro calls.
* One tracks operands of macro-related instructions so that we can later
group them.
After building up these data structures, we do a pass over the latter
structure. For each macro call instruction, we recursively traverse its
operands to ensure they're in the same scope. Thus, something like
`fbt('hello' + fbt.param(foo(), "..."))` will correctly merge the fbt
call, the `+` binary expression, the `fbt.param()` call, and `foo()`
into a single scope.

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
