[libcxx-commits] [PATCH] D58023: MSVC does not provide constexpr for typeid and typeid is probably not constexpr

Actually, there is nothing about `constexpr` qualifier for `typeid` operator in the standard and MSVC is probably correct in this case.

I can be wrong and if you convince me that `typeid` should be constexpr, I would discard this review and submit a bug to the Microsoft compiler team
