[compiler] Fix for consecutive DCE'd branches with phis (#33725)
This is an optimized version of @asmjmp0's fix in
https://github.com/facebook/react/pull/31940. When we merge consecutive
blocks we need to take care to rewrite later phis whose operands will
now be different blocks due to merging. Rather than iterate all the
blocks on each merge as in #31940, we can do a single iteration over all
the phis at the end to fix them up.

Note: this is a redo of #31959

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.
