whitequark 7ff5a9db2d equiv_opt: pass -D EQUIV when techmapping. 
This allows avoiding techmap crashes e.g. because of large memories
in white-box cell models.

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)
