	Shared points are handled on the host (device backends only). Kept in the base type so that it can be set without a select type: a select type (gs_device_t) assignment to it miscompiles with CCE 21 at -O2/-O3, silently leaving the shared points on the host so that the scatter overwrites the unpacked halo with the stale host buffer.
