There are three things we want to do:

1. Speed up pushing and popping frames. See https://github.com/faster-cpython/ideas/issues/111 for details.
2. Avoid tracing and other admin overhead on entering and leaving. See https://github.com/faster-cpython/ideas/issues/112.
3. Keep the remaining recursion depth in the cframe, to reduce the work for a recursion check from
`++tstate->recursion_depth > tstate->interp->ceval.recursion_limit`
to
`cframe.recursion_overhead-- > 0`
