  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.
