verilog: Lower required bison version to 3.6
...
We're currently on version 3.6 of bison at Google, and Yosys
still correctly builds with it. This should better reflect
the actual requirements rather than an overly restrictive
check. If features from 3.8 are required it seems like bumping
would be appropriate.

Use commutative hashing instead of expensive allocation and sorting
...
For one of our large circuits, this improves the `OptMergePass` runtime
from about 150s to about 130s. It's also simpler code.

hashlib: extend unit test with subset collisions, shorten runtime

Improve commutative hashing.
...
The simple XOR `commutative_eat()` implementation produces a lot of collisions.
https://www.preprints.org/manuscript/201710.0192/v1/download is a useful reference on this topic.
Running the included `hashTest.cc` without the hashlib changes, I get 49,580,349 collisions.
The 49,995,000 (i,j) pairs (0 <= i < 10000, i < j < 10000) hash into only 414,651 unique hash values.
We get simple collisions like (0,1) colliding with (2,3).
With the hashlib changes, we get only 707,099 collisions and 49,287,901 unique hash values.
Much better! The `commutative_hash` implementation corresponds to `Sum(4)` in the paper
mentioned above.

- cibw now builds and uses bison 3.8.2 explicitly on platforms with no or out-of-date bison — AlmaLinux 8 only goes up to Bison 3.0
- cibw environment now includes `OPTFLAGS=-O3` to avoid generating debug info for abc, saving space in memory during linking
- setup.py attempts to build `yosys-abc` independently first to avoid memory pressure from gigantic abc link step running in parallel with something else

Remove redundant construction of assign_map.
...
We call 'assign_map.set()' below which wipes the `SigMap` and reconstructs it.
This operation is expensive because it scans the whole module. I think it's
better to make heavyweight operations more visible so I'm removing
the less obvious operation.
