Leszek Swirski 71f758a2e2 [ignition] Reduce generator switch boilerplate 
The SwitchOnGeneratorState bytecode now also falls through if the
generator object is undefined (so that we don't need that jump) and
restores generator context (so that we don't need that PushContext).
This saves 10 bytes per generator.
