Of course the new gc adds code, as does to-be-closed variables. But I
think the larger increase comes from the new specialized opcodes. (Lua
5.3 has ~47 opcodes, Lua 5.4 has ~84.)

Checking the size of the .o files, these are the main increases:

- gc alone accounts for ~5 KB.
- the interpreter loop gets more 8 ~KB.
