Martin Povišer cde2a0b926 booth: Make more use of appropriate helpers 
Use the `addFa` helper, do not misuse `new_id` and make other changes
to the transformation code.

Martin Povišer 986507f95f booth: Streamline the low-level circuit emission 
For the basic single-bit operations, opt for gate cells (`$_AND_` etc.)
instead of the coarse cells (`$and` etc.). For the emission of cells
move to the conventional module methods (`module->addAndGate`) away
from the local helpers. While at it, touch on the surrounding code.

Martin Povišer fedd12261f booth: Move away from explicit `Wire` pointers 
To represent intermediate signals use the `SigBit`/`SigSpec` classes as
is customary in the Yosys codebase. Do not pass around `Wire` pointers
unless we have special reason to.
