[Compiler Bug]:Compiler doesn't memoize if const is between hooks

[pritjasani08]

What kind of issue is this?

• React Compiler core (the JS output is incorrect, or your app works incorrectly after optimization)
• babel-plugin-react-compiler (build issue installing or using the Babel plugin)
• eslint-plugin-react-hooks (build issue installing or using the eslint plugin)
• react-compiler-healthcheck (build issue installing or using the healthcheck script)

Repro steps

1. Open the React Compiler Playground link: https://playground.react.dev/#N4lgzg9grgTgxgUxALhAejQAgLIILYQCWAXggCaYBGAnpgEolCGc
2. Observe the code that has a const declaration between React hooks
3. Check the compiled output - you'll see that memoization is not working correctly
4. The compiler should memoize values even when const is between hooks, but it currently doesn't
