This makes '-init_hw_device opencl' work in a multiple-device system.
Under what circumstances is this more useful than the existing behaviour which
prompts the user to select the device they intend?
There is no particular ordering to devices, the first one is just random.
Having your process fail with an opaque message (because the device picked
lacks some operation) or run many times slower than expected (because the
smallest device happened to be first in the list) or do something different on
a machine which looks the same (because it has an extra driver for something
else) rather than just saying up front that there are multiple devices and the
user needs to pick seems worse to me, since it is much harder to see where the
problem is.
