This extracts the instruction sequence data structure to a separate file. Next will be to add the Python interface into this data structure.

Also simplifies instr_sequence_to_cfg through better abstraction.

Just to confirm, this is a pure refactor with no new functionality?

I don't think the addition of PyObject_HEAD headers is correct, but it looks good otherwise.

Note: switching to '04697bcfaf5dd34c9312f4f405083b6d33b3511f'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 04697bcfaf gh-117494: extract the Instruction Sequence data structure into a separate file (#117496)

    2: memory fault at wasm address 0x1000005b0 in linear memory of size 0xa00000
    3: wasm trap: out of bounds memory access

That's 341 successive (recursive?) calls to compiler_visit_expr(). I'm not sure what other details there are useful. That's about as deep a stack as I've seen in WASI stack traces, but there wasn't a stack overflow like I was expecting. (WASI has a smaller stack that other platforms, at least effectively, relative to the Python recursion limit). Perhaps a memory fault is another way that running-out-of-stack manifests?

I don't see how this PR could have impacted the recursion depth.

Yeah, it might be something else. I'm looking into it.
