[libcxx-commits] [PATCH] D59678: Make common_type's implementation common

[Eric Fiselier via Phabricator via libcxx-commits]

EricWF added a project: libc++.

Currently the C++03 implementation of common_type has much different behavior than the C++11 one. This causes bugs, including inside `<chrono>`.

This patch unifies the two implementations as best it can. The more code they share, the less their behavior can diverge.
