[turbofan] Move creation stub fallbacks to JSGenericLowering.

[turbofan] Move creation stub fallbacks to JSGenericLowering.

Move all the code that deals with falling back to object creation via
stubs to JSGenericLowering, where we can already deal well with stub
calls. This includes JSCreateLiteralArray, JSCreateLiteralObject,
JSCreateClosure, JSCreateFunctionContext and JSCreateArray.

Hey Michi,

As discussed offline, moving stuff to JSGenericLowering. I think it's even more
readable now (modulo that awful JSCreateArray, which we will hopefully be able
to kill when allocation pretenuring and elements kinds die).
Please take a look.

Thanks,
Benedikt
