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.
