Martin Povišer f0ae046c5a opt_share: Fix input confusion with ANDNOT, ORNOT gates 
Distinguish between the A, B input ports of `$_ANDNOT_`, `$_ORNOT_`
gates when considering those for sharing. Unlike the input ports of the
other supported single-bit gates, those are not interchangeable.

Fixes #3848.

Martin Povišer 6a553568c5 kernel/mem: Assert ABITS is not below wide_log2 
Later in the check() code we check the bottom wide_log2 bits on the
address port are zeroed out. If the address port is too narrow, we crash
due to out of bounds access. Explicitly assert the address port is wide
enough, so we don't crash on input such as

    read_rtlil <<EOF

      memory width 8 size 2 \mem

Charlotte 3f29bdbbc5 smt2: py3.12+: avoid SyntaxWarning. 
Python 3.12 emits a SyntaxWarning when encountering invalid escape
sequences.  They still parse as expected.  Marking these raw produces
the same result without the warnings.

proc_prune: avoid using invalidated iterator

Charlotte 63e4114233 proc_prune: avoid using invalidated iterator 
An `std::vector<T>::reverse_iterator` stores the
`std::vector<T>::iterator` which points to the (forwards-ordered)
*following* item.  Thus while `vec.rbegin()` dereferences to the final
item of `vec`, the iterator it wraps (`vec.rbegin().base()`) is equal to
`vec.end()`.

In the remove case here, we advance `it` (backwards), erasing the item
we just advanced past by grabbing its (pre-increment) base
forward-iterator and subtracting 1.

The iterator maths here is obviously all OK, but the forward-iterator
that `it` wraps post-increment actually points to the item we just
removed.  That iterator was invalidated by the `erase()` call.

That this works anyway is (AFAICT) some combination of luck and/or
promises that aren't part of the C++ spec, but MSVC's debug iterator
support picks this up.

`erase()` returns the new iterator that follows the item just erased,
which happens to be the exact one we want our reverse-iterator to wrap
for the next loop; we get a fresh iterator to the same base, now without
the preceding item.
