Generate OpenCL C feature dictionary
Features are stored in a text file for now. Ultimately, we probably want to use the XML registry for this. Generation script taken from KhronosGroup#1174 with a few modifications. Contributes to KhronosGroup#1166. Signed-off-by: Ben Ashbaugh <[email protected]> Signed-off-by: Kevin Petit <[email protected]> Change-Id: Ie2c14148d75457030aa1a97cf601daba2c007397
