Robert O'Callahan 46cb05c471 Pass IdString by value instead of by const reference.
When IdString refcounting was expensive, it made sense to pass it by const reference
instead of by value, to avoid refcount churn. Now that IdString is not refcounted,
it's slightly more efficient to pass it by value.

Marcelina Kościelnicka d25b9088c8 Refactor common parts of SAT-using optimizations into a helper.
This also aligns the functionality:

- in all cases, the onehot attribute is used to create appropriate
  constraints (previously, opt_dff didn't do it at all, and share
  created one-hot constraints based on $pmux presence alone, which
  is unsound)
- in all cases, shift and mul/div/pow cells are now skipped when
  importing the SAT problem (previously only memory_share did this)
  — this avoids creating clauses for hard cells that are unlikely
  to help with proving the UNSATness needed for optimization

Xiretza 3aa10e90ba modtools: fix use-after-free of cell pointers in ModWalker
cell_inputs and cell_outputs retain cell pointers as their keys across
invocations of setup(), which may however be invalidated in the meantime
(as happens in e.g. passes/opt/share.cc:1432). A later rehash of the
dicts (caused by inserting in ModWalker::add_wire()) will cause them to
be dereferenced.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes.
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
