mass update mechagodzilla -> mechagodzilla_2 - super_mechagodzilla

Mechagodzilla 2 is the rebuilt Mechagodzilla in Terror of Mechagodzilla and has MG2 on its shoulder.

Super Mechagodzilla is the Mechagodzilla in Godzilla vs. Mechagodzilla II after combining with the aircraft Garuda.

It's from a separate timeline and only shows up once, the cause of the confusion is some idiot at Toho decided to put II in the English title of the movie. Pipeworks' Godzilla game trilogy fell for this confusion as well.

What are you trying to achieve with this BUR exactly? Because as-is (mass update mechagodzilla -> mechagodzilla_2 - super_mechagodzilla) you're updating every single Mechagodzilla post to also have Mechagodzilla 2 and to remove Super Mechagodzilla from those posts. Do you want to combine these tags? Imply them? Fix mistags? Rename them?
