[PATCH] D17053: [libcxx]: vector: Use < instead of != to improve failure mode

[Louis Dionne via Phabricator via cfe-commits]

ldionne added a comment.

Also, regarding `allocator::pointer` vs raw pointers -- if someone defines a fancy pointer type whose `operator<` is significantly more costly than `operator!=`, I think this loop in libc++ is not the first thing that's going to bite them. I don't think that's the right motive to drop this patch, instead I think it's about the debug mode like I explained above.
