Matt Arsenault de32382a70 TableGen/GlobalISel: Emit enum names for reg class ID instead of value
This was emitting the raw value for the reg class ID with a comment
for the actual class name. Switch to emitting the qualified enum name
instead, which obviates the need for the comment and also helps keep
the lit tests on the emitter output more stable.
