 Metal provides four [`MTLStorageMode`][mtl-storage-mode] options:

 Among them, `MTLStorageModeManaged` is only available on macOS.
 
 IREE HAL defines serveral [`MemoryType`][hal-buffer]. They need to map to the
 above storage modes:
 
-* If `kDeviceLocal` but not `kHostVisible`, `MTLStorageModePrivate` is chosen.
-* If `kDeviceLocal` and `kHostVisible`:
-  * If macOS, `MTLStorageModeManaged` can be chosen.

 IREE HAL also allows to create buffers with `kHostCoherent` bit. This may still
 be backed by `MTLStorageModeManaged` `MTLBuffer`s in macOS. To respect the
 `kHostCoherent` protocol, the Metal HAL driver will perform necessary
 `InValidate`/`Flush` operations automatically under the hood.
