Fix Reflect.construct wrt proxy, generator, and non-subclass new.target

Fix Reflect.construct wrt proxy, generator, and non-subclass new.target

This makes sure that proxy + Function/Array works
Makes sure that new.target can be a generator
Makes sure that if new.target is not a subclass, but does not have a prototype, that we'll get that same prototype back the next time we look at new.target.prototype.

Note that generators no longer have a [[Construct]] slot
(https://github.com/tc39/ecma262/commit/bddde2330989a5a8daf26b37963f668bb3382371),
so that part of this change will need updating.

[Toon Verwaest, 2015-12-01 15:34:22]

I noticed it was wrong anyway. It doesn't use new.target but F instead, for some
reason.
