Making the code size predictable is hard, and to make things even more complicated, the start of a function can contain various stuff like calls to a profiling hook, receiver adjustment or dynamic frame alignment. Instead of tackling all these problems separately, we now simply record the offset where patching should happen later in the Code object itself.
