Review comment:
@kparzysz-quic is it possible to query hexagon to return some of these
device specific attributes? E.g. the architecture rev, vector width, available
memory.
There is some desire to add general support to the DeviceAPI to query device
specific parameters to use to build a target which can then influence lowering
and codegen. The Vulkan target already achieves this via a packed function, but
it could be extended to support all DeviceAPI subclasses. But this will only
help if the hexagon sdk supports device attribute querying. If so, we can
consider revisiting the target construction after converging on a proposal for
the above change to the Device API.
