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.

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.

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.
