Escape analyze function scopes on non-arrow functions

[HalidOdat]

This PR omits functions scopes that that are not needed for non-arrow functions. We can see a nice performance increase in the QuickJS benchmarks :).

This is even better than my suggestion which was to not GC these function environments. Instead they don't need to be created at all because if the bindings don't escape they are just poppedToLocal anyway and don't pollute the environment above.
