f3f55ae7c2 dfflegalize: Prefer mapping dff to sdff before adff 
This ensures that, when both sync and async FFs are available and abc9
is involved, the sync FFs will be used, and will thus remain available
for sequential synthesis.

Suspect it is to do with map/set ordering in techmap; should
be fixed by #1862?

a9b61080a4 Add newlines to help text for dfflegalize 
I think these were probably missed by accident. Spotted because GCC
spits out lots of messages like this:

passes/techmap/dfflegalize.cc:114:7: warning: zero-length gnu_printf format string [-Wformat-zero-length]
  114 |   log("");
      |       ^~

(because we tell GCC that the first argument to log() looks like a
printf control string in log.h, and a zero length such string triggers
a warning).

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.
