Ha A clang bug indeed! Although IDK how sane the other behavior is, 
specifically:

```
constexpr bool foo() noexcept(false) { return true; }
static_assert(!noexcept(foo()));
```

This part of the change LGTM, but could you also add a test that the function 
is not noexcept when it cannot do constant evaluation?
