- `__is_copy_assignable`
- `__is_nothrow_copy_assignable`
- `__is_trivially_copy_assignable`
This is information that the compiler already has, and should be exposed
so that the library doesn't need to reimplement the exact same
functionality.
Similarly to `__is_copy_construcitble`, etc., these traits can't be
implemented using `__is_assignable`, etc., because we can't form
references to void, which are a fundamental part of copy assignment.
Depends on D135238 <https://reviews.llvm.org/D135238>.
