  Message : CL: Refactor info structs and fix conformance bug - Remove variable name prefix from Info structs to be more consistent with other ANGLE structs. - Fix CL object validation check with magics, since the Mesa solution doesn't work without RTTI. - Add support for some extensions required by OpenCL 1.1 and for some optional extensions. - Fix more conformance bugs. Bug: angleproject:6015 Change-Id: I41b1c45d95059a9994f5dc78bf9b74476cc6f2d4 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2956349 Commit-Queue: John Plate <jplate@google.com> Reviewed-by: Cody Northrop <cnorthrop@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
