[ffigen] [objc] Incorrect code generation for CFStringGetPascalStringPtr

[brianquinlan]

The generated code is (ffigen 20.0):

  late final _CFStringGetCStringPtr =
      _lookup<
        ffi.NativeFunction<
          Boolean Function(
            CFStringRef,
            ffi.Pointer<ffi.Char>,
            CFIndex,
            CFStringEncoding,
          )
        >
      >('CFStringGetCString');

  ConstStringPtr CFStringGetPascalStringPtr(
    CFStringRef theString,
    int encoding,
  ) {
    // The expression does not evaluate to a function.
    return _CFStringGetPascalStringPtr(theString, encoding);
  }

Can't repro this in package:objective_c. Can you point me to a branch where I can check out your in progress migration?

Looks like the issue is that there's a CFStringGetPascalStringPtr and a CFStringGetPascalString function. They both define global variables called "_$name" and "_${name}Ptr, so there's a conflict. The conflict should be resolved automatically by the renamer, but they're putting these variables in the wrong scope.
