Check for missing port in SDC code to work around compiler bug

Robert O'Callahan 37347aacb2 Check for missing port in SDC code 
I am getting weird crashes on `main` in `tests/sdc/alu_sub.ys` which I traced to a null `Wire*`
in `SdcObjects::constrained_ports`. The null `Wire*` is being set in the `SdcObjects`
constructor. I don't understand what's going on here, so I added this check to detect the
missing wire early ... and that made the crash go away. Compiler bug maybe? I have
`Debian clang version 19.1.7 (3+build5)`, default build configuration.

Anyway this code seems fine to have.

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 a6d696ba2b Give `IdString` a default move constructor and make it a POD type. 
Now that we're not refcounting `IdString`, it can use the default move constructor.
This lets us make `IdString` a POD type so it can be passed in registers
in the standard C++ ABI.

Robert O'Callahan 99d7ab9c42 Increase test timeout to 10 seconds 
On my machine, this test regularly times out when doing "make -j" (which defaults to 128).
The high degree of parallelism seems to slow down the spwaning of ABC processes.

Robert O'Callahan 48cdb499f2 Remove `IdString::id_string()`. 
This was needed for the short time when `ID()` could return a value of `StaticIdString`.
That is no longer a problem.

Robert O'Callahan 46cb05c471 Pass IdString by value instead of by const reference. 
When IdString refcounting was expensive, it made sense to pass it by const reference
instead of by value, to avoid refcount churn. Now that IdString is not refcounted,
it's slightly more efficient to pass it by value.
