There's even the issue that you can have eg. OpenCL 1.2 compatible
*drivers* at run-time but some or all of your *devices* are OpenCL 1.1
or 1.0. This can currently be seen with --list=opencl-devices. For
example, any card not physically capable of byte-addressed stores will
never get better than OpenCL 1.0 regardless of driver updates (well
unless they work around it in software, but there's no chance they would
do that for an old card).

You could re-use some of the --list=(cuda|opencl)-devices code and put
this stuff into --list=build-info if you want to, but I would personally
not bother. I do not object either, but we should try to use shared
functions eg. in opencl-common.c so future fixes don't have to be
applied to several places.
