Thanks for the feedback.
As discussed offline, let's only enable restrict under a compatibility flag. PTAL.

Something I should probably have explained in the commit message is that the functionality provided by restrict is already present in C++, where it is already exposed using different keywords. If you look at clang/include/clang/Basic/TokenKinds.def, there are __restrict__ and __restrict aliases that end up producing tok::kw_restrict. The only thing this patch does is enabling the restrict keyword in C++ for OpenCL for compatibility with OpenCL C (see more on that on the bug). I don't expect any special handling will be required since the functionality is already supported both in C++ and OpenCL C.

There doesn't seem to be a test for this (enabling restrict in C++ doesn't make any existing test fail). I couldn't find any test checking that OpenCL or C++/OpenCL keywords generally aren't enabled in C or C++. Doing this generically would essentially equate to writing unit tests for getKeywordStatus.

Hmm, maybe we need to make sure that one of the tests is using a C++ feature and building with CLC++. This would have caught the mistake.
Thanks for doing this!

Would it be ok if I fix those in a separate commit? I would really like to commit the core part before the release branch is taken.
Very useful to have all of this documented! Thanks!

The comments could use a bit more polishing but nothing that justifies making another iteration IMHO. LGTM!

Clean up the tests.
Most of these are pre-existing issues with the tests but I agree they're worth fixing. I'll update the tests.

Replaced the AST dump test with an IR test.
Ok, I'll replace the test with an IR-level test.

The implementation of getFlatAddressSpace in the AMDGPU backend does a bit more than just return a constant. This logic would need to be duplicated or the TTI called from their pass factory which would be the first use. TBH, I'm not too worried about the change to the factory breaking. This will be used in an out-of-tree project that tracks llvm fairly closely. If this breaks, I'll propose a change to exercise this from some in-tree code.

But would it be possible to extract an .ll file generated from C++ (may be with some amendments) and run opt with the pass enabled?
This doesn't fix anything broken in LLVM but I did check that it didn't break any of the existing tests either :).
The pass is used by the AMDGPU and NVPTX backends. All their tests are passing with this change.

Address review comments.
@arsenm Thanks for the review.
