This patch is LGTM, but IMHO this is a case when a work shouldn't be split across components - I mean that either this PR should also include changes in clang, that are forcing OpenCL environment to be included in the triple information for OpenCL lang or the appropriate PR in clang should already exist and be linked here as we also need to have an attention and feedback from the frontend folks.
