glift: Add `-simple-cost-model` option 
Rather than assigning specific weights to specific versions of taint tracking logic and summing the weights of all GLIFT cells, sum the following values for each GLIFT cell:
  - 0 if the associated hole/$anyconst cell value is non-zero, i.e. reduced-precision taint tracking logic is chosen at this cell
  - 1 if the associated hole/$anyconst cell value is zero, i.e. the full-precision taint tracking logic is chosen at this cell

This simplified cost modeling reduces the potential for the QBF-SAT solver to minimize taint tracking logic area but significantly simplifies the QBF-SAT problem.

qbfsat: Fix name-based hole specialization. 
Look for unique connections in the containing module with the $anyconst port Y SigBit on the RHS and use those. If no such connection is found, fall back to using the name of the $anyconst port Y SigBit.

Lukasz Dalek 7cb56f34b0 Fix integer signing grammar 
This commit fixes signed/unsigned grammar in parameters as defined in SV
LRM A2.2.1. Example of correct parameters:

parameter integer signed i = 0;
parameter integer unsigned i = 0;

Example of incorrect parameters:

parameter signed integer i = 0;
parameter unsigned integer i = 0;
