Martin Povišer 652a1b9806 macc: Stop using the B port 
The B port is for single-bit summands. These can just as well be
represented as an additional summand on the A port (which supports
summands of arbitrary width). An upcoming `$macc_v2` cell won't be
special-casing single-bit summands in any way.

In preparation, make the following changes:

 * remove the `bit_ports` field from the `Macc` helper (instead add any
   single-bit summands to `ports` next to other summands)

 * leave `B` empty on cells emitted from `Macc::to_cell`

Martin Povišer 481d596c43 abc9_ops -prep_box: Adjust for repeated invocation 
`abc9_ops -prep_box` command interprets the `abc9_box` attribute and
prepares a .box file for ABC consumption. Previously this command was
removing the attribute as it was processing each module which prevented
repeated invocation of this command unless the box definitions were
refreshed from a source file.

Also the command was keeping existing `abc9_box_id` attributes instead
of overwriting them with values from a new number sequence.

Change both behaviors to allow repeated invocations of the command on
the same design.

Reduce comparisons of size_t and int 
`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.
