The abc pass runs module snippets through ABC one at a time. We want to run those ABC jobs in parallel and control how many run at once. This change parallelizes ABC runs over BLIF snippets using a process pool and the user can specify how many processes should be in the pool.
It splits the non‑DFF/clock‑domain flow into stages and runs the ABC step with a worker pool. Adds -max_threads and -reserved_cores (and defaults abc.max_threads / abc.reserved_cores) to control parallelism.
