Robert O'Callahan 32f5044eaf Clarify "Not passing module as function argument" comment 
This correct in terms of intent, it's just not fully enforced due to const laundering.

Robert O'Callahan 72a21fe01d Introduce `RmStats` struct to encapsulate removal statistics 
Turns out this is not strictly necessary for this PR but it's
still a good thing to do and makes it clearer that the stats
are not modified in a possibly racy way.

Robert O'Callahan c2bb7d6a82 Make `keep_cache_t` process all modules up-front instead of on-demand 
We will want to query `keep_cache` from parallel threads. If we compute
the results on-demand, that means we need synchronization for cache
access in those queries, which adds complexity and overhead. Instead, prefill
the cache with the status of all relevant modules. Note that this doesn't
actually do more work --- we always consult `keep_cache` for all cells of
all selected modules, so scanning all those cells and determining the kept
status of all dependency modules is always required.

Later in this PR we're going to parallelize `scan_module` itself, and that's also
much easier to do when no other parallel threads are running.

Andrew Pullin 5970be33fb abc9: preserve topological-loop asserts with targeted SCC fallback 
A real-world ABC9 flow hit residual combinational loops after SCC breaking, tripping the prep_xaiger loop assertion.

Keep the existing topological assertions in place (prep_xaiger and reintegrate still assert no_loops).

To handle residual non-box loops, add a targeted fallback in prep_xaiger: when loops remain after normal SCC breaking, insert additional $__ABC9_SCC_BREAKER cuts on non-box loop cells, rebuild toposort, and then re-check the existing assertion.

Also keep pre-ABC9 SCC tagging on all cell types (scc -all_cell_types) and add a regression test (tests/techmap/abc9-nonbox-loop-with-box.ys).
