[OpenCL] Remove extra native_ functions from opencl-c.h

[ashi1]

Summary

There should be no native_ builtin functions with double type arguments.

[nhaustov]

LGTM, thanks.

Could you also note in commit message that online HTML docs are not very clear, but pdf of OpenCL specification has it right.

[Anastasia]

LGTM!
