[PATCH] D49773: Add new file test/support/test_comparisons.h

[Eric Fiselier via Phabricator via cfe-commits]

EricWF added a comment.

Some of this stuff is marked `constexpr` despite it requiring C++14 constexpr semantics.  Can they be non-constexpr in C++11 and still function? Or should the header explicitly require C++14 to be included?
