Jakob, can you confirm or deny that an instruction's representation can

I think representations only change during graph building (some special
cases
are initialized or frozen there, and instructions with fixed
representations set
those in their ctor) and during the InferRepresentations phase (where the
vast
majority of representation changes happen). And of course phases that add
instructions later (e.g. some of the bounds check stuff) will likely set a
representation for those new instructions.
