[PATCH] D19271: Change CALL_ONCE_INITIALIZATION implementation to use static initialization

[Reid Kleckner via llvm-commits]

rnk added a comment.

Initialization of local statics is not thread safe in VS 2013, so no, this approach doesn't work. There was some other mingw issue with std::call_once. Ask Chris about this, it's horrible.

These problems will go away when our support floor is VS 2015.
