----------------
Could it be an error instead for CL <2.2? It isn't a valid feature and we have already rejected similar cases with an error. 

How about changing to something like:
  "vector component name '%0' is not supported in earlier than OpenCL version 2.2"

See similar diagnostics above - err_opencl_invalid_read_write, err_opencl_unknown_type_specifier.

Using extension might be confusing because we have core spec and extension spec in OpenCL.
