I'd say that the following would be preferred:
0. `vector.gather` --> `vector.load` + `scf.if` (already there)
1. `vector.transfer_read`/`transfer_write` --> `vector.load`/`store`, `vector.maskedload`/`maskedstore`
2. `vector.maskedload`/`maskedstore` --> `vector.load`/`store` + `scf.if`
3. `vecotr.load`/`vector.store` --> ConvertVectorToSPIRV (already there)
4. `scf.if` --> ConvertSCFToSPIRV (already there)

(or `memref.load`/`store`, I don't think there's much difference?)

Unless there's something that we could do much better by going directly to SPIR-V.
