Backport bee4bd7 to 14.0.0

[AnastasiaStulova]

This patch is required for the OpenCL 3.0 completion and it is not affecting widespread functionality as it is specific to OpenCL.

@tstellar I am not sure whether the automation works for multiple patches so if needed I can split this into multiple issues. However, we do have some dependent commits (see the first list), so it might be that this case is not covered yet?

FYI this issue is now updated to cover backport of bee4bd7 only that applies cleanly and passes the tests:
llvmbot#46

The backport of other remaining patches for OpenCL 3 completion are now covered by #53823 and #53822.

[AnastasiaStulova]

Closing this because it is now covered by #53823
