[PATCH] D23385: Implement __attribute__((require_constant_initialization)) for safe static initialization.

Get all tests passing regarding duplicate warnings between `__attribute__((requires_constant_initialization))` and `-Wglobal-constructors`. The warning will not emit a duplicate warning about global constructors, but it will still warn if the variable has a global destructor, which make sense to me.

I believe this is ready to go and I have addressed all concerns.
