[PATCH] D18369: [OpenCL] Upstreaming khronos OpenCL header file.

[Anastasia Stulova via cfe-commits]

Anastasia added a comment.

Sam, there are a few small comments, otherwise it seems to be in a good shape.

@rsmith, do you think you could take a look here? The OpenCL side is fine, but I was just wondering if you see any issue with us adding a header of ~17K lines. It is all part of OpenCL standard libraries though and would be very helpful to have it upstream for all of us. Any suggestion on testing would be useful too as it's a bit simplified for now due to its size.
