| Summary |
Clang crash when trying to evaluate a constexpr with `auto` type, variadic template before type is fully defined

Example:
```c++
struct MyClass {
template <int...> static constexpr auto foo() { return 1;}
static constexpr auto my_value = foo();
};
```
We get a "Unexpected undeduced type!" crash
Compiler Explorer: https://godbolt.org/z/7rhT7qEeE
I believe this should be an error that says the function `foo()` isn't defined yet because the class isn't fully defined, but not a crash.
