// This is a sketchy test because it relies on knowing that the following pattern
// hits the heuristics that decide to cache the scopes within the generator function.
// If those heuristics were to change this test could no longer be hitting the
// desired code paths.  If you suspect it is not hitting the cached scope code paths
// dump the bytecode and check for InitCachedScope and LdHeapArgsCached opcodes.
