90e0938f9a Update to .smv backend 
Splitting VAR and ASSIGN into IVAR, VAR, DEFINE and ASSIGN. This allows better handling by nuXmv for post-processing (since now only state variables are listed under VAR).

93d19dc2fb Add support for module instances. 
Don't pad logical operands to one bit.
Use operand width and signedness in $reduce_bool.
Shift amounts are unsigned and shouldn't be padded.
Group "is invalid" with the wire declaration, not its use (otherwise it is incorrectly wired to 0).

Use realpath 
Use `os.path.realpath` instead to make sure symlinks are followed. This is also required to work for nix package manager.

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)
