[PATCH] D52875: Fix definitions of __builtin_(add|sub|mul)_overflow

[Erich Keane via Phabricator via cfe-commits]

Can you write tests for this please?  Particularly validate the results in a constexpr context.

Additionally, these all have the 't' flag, which means that these signatures are meaningless, right?  What are you seeing where this works incorrectly?
