[PATCH 0/1] MR9445: opencl: Silence warnings on macOS for functions deprecated by OpenCL 1.2.

[Brendan Shanks (＠bshanks)]

There are 6 functions that were deprecated in OpenCL 1.2 and are marked deprecated in the macOS headers (without any way to disable the `deprecated` attribute other than `#pragma diagnostic ignored`).

Fixes these warnings:
