Austin Rovinski 5059bb1d4f dfflibmap: force PathMatchSpecA on WIN32

LPCWSTR argument. char* is only convertable to LPCSTR, so use that
implementation

signed multipliers.

Rasmus Munk Larsen 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.

Martin Povišer 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.
