That way, we don't need to create a context-less constructor function. Instead, we use the constructor_or_backpointer (or null) field, and rename it to constructor_or_fti_or_backpointer so nobody is confused. Note that technically, we still have JSFunctions without contexts, as they're temporarily created in the deoptimizer.
