Currently, _PyCode_SetExtra() uses two memory block for code extras. Using a different structure, it would be possible to use a single memory block: less memory fragmentation, better CPU cache usage, less indirections, etc.

It matters since the long term plan for co_extras is to implement of kind-of JIT compiler insider CPython: see bpo-28158.
