Clang++ front-end crashes with the following code:

Compilation command: clang++ -std=c++17 sample.cpp

See here on godbolt: https://godbolt.org/z/o1xjK8

Code:
=================
```
#include <type_traits>

struct S {
    void Func() {
    }
};

#include <iostream>
int main()
{
    auto lambda = [](const auto& cls) -> decltype(
        std::remove_const_t<std::remove_reference_t<decltype(cls)>>::Func()
    ) {};

    auto isInv = std::is_invocable_v<decltype(lambda), S>;
    if (!isInv){
        std::cout << "detected correctly";
    }
    return 0;
}
```
