[PATCH] D23385: Implement __has_constant_initializer(obj) expression traits.

[Eric Fiselier via cfe-commits]

EricWF added a comment.

Open questions:

- What should __has_constant_initializer do for non-static inputs? Currently it returns false.
- Do I need to do more to handle value dependent inputs?
- Should expression traits SFINAE?
