Remove expression scanning from function finalization pass.
Now that built-in functions are handled elsewhere, the only thing left
here was a check for calls to `dFdy`. This job is better suited to the
built-in-function scanner anyway.
With this change, the function finalization pass only needs to scan
statements. Expressions can be skipped over entirely.
