This was obtained by running the following SED command in passes/opt/
and then using "meld foo.cc foo.cc.orig" to manually fix all resulting
compiler errors.
sed -i.orig -r 's/"\\\\([a-zA-Z0-9_]+)"/ID(\1)/g; s/"(\$[a-zA-Z0-9_]+)"/ID(\1)/g;' *.cc

Fix memory leak when one of multiple DFF cells is removed in opt_rmdff
...
When there are multiple DFFs and one of them is removed, its reference lingers
inside bit2driver dict. While invoking handle_dff() function for other DFFs,
this broken reference is used isnside sat_import_cell() function.

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)
