Optimize IdString::empty()

I actually saw this take 0.6% of the time in an `opt_clean` pass (under Module::check()).
Trivial issue, but the fix is also trivial and simple.

aiger2: Only fail for reachable undirected bufnorm helper cells
...
The aiger2 backend checks for unsupported cells during indexing. This
causes it to fail when `$connect` or `$tribuf` (as workaround for
missing 'z-$buf support) cells are present in the module.
Since bufnorm adds these cells automatically, it is very easy to end up
with them due to unconnected wires or e.g. `$specify` cells, which do
not pose an actual problem for the backend, since it will never
encounter those during a traversal.
With this, we ignore them during indexing and only produce an actual error
message if we reach such a cell during the traversal.

portarcs: Ignore all bufnorm helper cells
...
The `portarcs` pass was already ignoring `$buf` cells when loading
timing data, but now bufnorm will also emit `$input_port` and `$connect`
helper cells, which need to be ignored as well.

verific: Extend -sva-continue-on-err to handle FSM explosion

This also rolls back any added cells and wires, since we might have
added a lot of helper logic by the point we detect this.
