When I landed the EmulateUnsupportedFloats, I'd negligently included an assert that needed to run for the pass to be correct. Previous emergency fix commits removed the assert. This commit re-adds the "can't happen" testing as an emitOpError() and aborting the rewrite, thus allowing it to function in no-assertions builds.
