nit: it would be good if the pseudo ops `GetTileOp`, `CopyTileOp` and `UnrealizedConversionCastOp` were together, how about moving these to line 915 alongside `UnrealizedConversionCastOp`? A comment mentioning these are legal to permit temporary use during conversion but can't be code-generated would also be helpful.
