arsenm created this revision.
arsenm added reviewers: Anastasia, yaxunl, scott.linder.
Herald added subscribers: kerbowa, hiraditya, nhaehnle, wdng, jvesely.
Some of the device specific standard predefines were missing.
__IMAGE_SUPPORT__ was only hardcoded for SPIR. __OPENCL_VERSION__
wasn't defined at all, so allow targets to pick values for these.
