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)

Olof Kindgren faac2c5595 Avoid mixing module port declaration styles in ice40 cells_sim.v 
The current code requires workarounds for several simulators
For modelsim, the file must be compiled with -mixedansiports and
xsim needs --relax.
