5059bb1d4f dfflibmap: force PathMatchSpecA on WIN32 
Depending on the WIN32 compilation mode, PathMatchSpec may expect a LPCSTR or
LPCWSTR argument. char* is only convertable to LPCSTR, so use that
implementation

689feed012 dfflibmap: Add a -dont_use flag to ignore cells 
This is an alternative to setting the dont_use property in lib. This brings
dfflibmap in parity with the abc pass for dont_use.

d6566eb344 booth: Redo baseline architecture summation 
Redo the summation logic: strive for some degree of balance on the
generated Wallace tree, emit an `$add` cell for the final summation.

48b73be8c6 booth: Replace the default signed architecture 
Generalize what was formerly the unsigned-only architecture to support
both signed and unsigned multiplication, use that as default, and set
aside the special low-power architecture that was formerly used for
signed multipliers.

0a37c2a301 Fix translation bug: The old code really checks for the presense of a node, not an edge in glift and flatten. 
Add back statement that inserts nodes in order in opt_expr.cc.

0434f9d3d1 booth: Fix vacancy check when summing down result 
In commit fedd12261 ("booth: Move away from explicit `Wire` pointers")
a bug was introduced when checking for vacant slots in arrays holding
some intermediate results. Non-wire SigBit values were taken to imply
a vacant slot, but actually a constant one can make its way into those
results, if the multiplier cell configuration is just right. Fix the
vacancy check to address the bug.

abd9c51963 Speed up simplemap_map by 11.6x by directly inserting the cell source attribute in the new object's 'attributes' map instead of calling set_attr_pool to create a new pool and then copying that.

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.
