Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.

Browse Source 
This is the last MVTSDNode.

This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.

Also, remove some uses of dyn_cast that should really be cast (which is
cheaper in a release build).
