Robert O'Callahan 8da919587d Parallelize `opt_merge`. 
I'm not sure why but this is actually faster than existing `opt_merge` even with
YOSYS_MAX_THREADS=1, for the jpeg synthesis test. 16.0s before, 15.5s after for
end-to-end synthesis.

Merge pull request #5555 from rocallahan/defer-redirects 
Defer redirecting cell outputs when merging cells in `opt_merge` untill after we've done a full pass over the cells.

Robert O'Callahan 042ec1cf60 Defer redirecting cell outputs when merging cells in `opt_merge` until after we've done a full pass over the cells. 
This avoids changing `assign_map` and `initvals`, which are inputs to the hash function for `known_cells`,
while `known_cells` exists. Changing the hash function for a hashtable while it exists leads to
confusing behavior. That also means the exact behavior of `opt_merge` cannot be reproduced by a
parallel implementation.

Robert O'Callahan e9aacd8a05 Move `OptMerge` cell filtering logic to happen while building the cell vector. 
This code is quite confusing because there are two "is the cell known" filters
applied, one while building the cell vector and one after building the cell
vector, and they're subtly different. I'm preserving the actual behaviour here
but it looks like there is, or was, a bug here.

Jannis Harder 5f79a6e868 Clean up $buf with 'z inputs, $input_port and $connect cells 
This ensures that entering and leaving bufnorm followed by `opt_clean`
is equivalent to just running `opt_clean`.

Also make sure that 'z-$buf cells get techmapped in a compatible way.

There are some leftovers, but this is an easy regex-based approach that removes most of them.
