I wondered if I should go further than this in reworking `support/count_new.h`. Would it be better to remove the existing cases that directly call `_aligned_malloc` and `posix_memalign`, on the basis that `__libcpp_aligned_helper` has already made the same choice? Or even to remove `allocate_aligned_impl` and `free_aligned_impl` completely, and have the rest of this support module just call `__libcpp_aligned_helper` and `__libcpp_free_helper` directly?

I've been conservative for the moment, because I'm not set up to test on all of the affected platforms. But I'm happy to change the patch to be more drastic if reviewers think that's a good idea!
