Map ===, !==, >>>, and >>>= operators

Browse source 
This change maps the ECMAScript operators ===, !==, >>>, and >>>= to
the MuIL operators ==, !=, >>, and >>=, respectively.  This isn't
entirely correct, however, we will most likely emulate these using
runtime helpers down the line; marapongo/mu#50 tracks this issue.
