`PropertyPathRegistry` is responsible for uniqueing identifier and property paths. This is necessary for the hoistability CFG merging logic which takes unions and intersections of these nodes to determine a basic block's hoistable reads, as a function of its neighbors. We also depend on this to merge optional chained and non-optional chained property paths This fixes a small bug in #31066 in which we create a new registry for nested functions. Now, we use the same registry for a component / hook and all its inner functions ' --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

React Compiler
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.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
