Fix 1: Track Scope::needs_home_object and Scope::uses_super_property
accurately. When "eval" is seen, figure out whether it can access
"super" and if yes, set the corresponding home object as needed.

Fix 2: The object literal scope shouldn't be entered for things
inside spreads.

This saves memory (the home object doesn't need to be stored for each
method, but only once per class) and hopefully makes the home object
a constant in the optimized code.
