JIT recorder: allow multiple consecutive recording ops per macro op

[Fidget-Spinner]

Feature or enhancement

Proposal:

We currently have things like

        macro(CALL_ALLOC_AND_ENTER_INIT) =
            _RECORD_CALLABLE +
            unused/1 +
            _CHECK_PEP_523 +
            _CHECK_AND_ALLOCATE_OBJECT +
            _CREATE_INIT_FRAME +
            _PUSH_FRAME;

Sometimes, we may want to record more than one field. We should support this in the case generator.

Has this already been discussed elsewhere?

I will work on this :)

And this should be done after we merge: #148373

We don't have to wait, they are different improvements. As long as it works I'll merge. Thanks!
