This error message doesn't look right. The implicit use of "this" should be
allowed here; if you replace the call to foo() with a constant, we should
accept. `this` refers to the object being constructed.
I guess that isn't specific to lambdas, though; I'm okay with opening a
followup bug. Compare the following with clang vs. gcc:
```
struct Noisy {
int x;
consteval Noisy(int x) : x(x) {}
constexpr ~Noisy() {}
};
struct Function {
template <typename F> constexpr Function(F) {}
};
struct Options {
int x;
Function function{Noisy{x}};
};
int foo();
Options kOptions{5};
```
