[PATCH] D30837: [libcxx] Support for shared_ptr<T()>

[Erik Pilkington via Phabricator via cfe-commits]

erik.pilkington updated this revision to Diff 91660.
erik.pilkington added a comment.

In this new patch:

- We only select `allocator<int>` when _Yp is a function type, fixing the ABI break @EricWF pointed out.
- Only try to select a different allocator if we're using the `__shared_ptr_pointer` layout; `make_shared<void()>` doesn't make sense.
- Improve the testcase

Thanks for the feedback!
Erik
