[for-in] Record slow path feedback only when we hit %ForInFilter.

[for-in] Record slow path feedback only when we hit %ForInFilter.

The only place in fullcodegen, where we know for sure that a for-in loop
entered the slow-path is right before the potential call to %ForInFilter.
So there's no point in also updating the mode eagerly during ForInPrepare.

Hey Yang,

Simple cleanup, so fullcodegen will be consistent with what I'm porting to
Ignition currently.
Please take a look.

Thanks,
Benedikt
