[PATCH] D45541: [globalisel] Update GlobalISel emitter to match new representation of extending loads

I think we lost 0.5% on compile time on CTMark because of this. Is there any scope left here for performance improvements? With the addition of the combiner landing later, I expect a further CT hit so anything we can do here would be good.
