[PATCH] D131423: [clang] fix frontend crash when evaluating type trait

[YingChi Long via Phabricator via cfe-commits]

inclyc added a comment.

@aaron.ballman @shafik  (Help wanted). These type traits will not cause clang to crash if current patch applied, but the `bool x` in that test case will evaluate to `false`.  I think the problem behind the github issue is that we don't check the number of arguments for builtin type trait like `__is_constructible`

I wanted to ask what is our expected behavior for this, give an error like using `std::is_constructible` or just consider `__is_constructible` should always have a bool value? Should we report a warning but compile translation unit, or report an error and terminate?
