Marcelina Kościelnicka 3d9698153f json: Add support for memories. 
Previously, memories were silently discarded by the JSON backend, making
round-tripping modules with them crash.

Since there are already some users using JSON to implement custom
external passes that use memories (and infer width/size from memory
ports), let's fix this by just making JSON backend and frontend support
memories as first-class objects.

Processes are still not supported, and will now cause a hard error.

Fixes #1908.

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)
