Looking at an AST dump from:
```c++
template <class _Tp, _Tp __v>
struct integral_constant {
static constexpr const _Tp value = __v;
typedef _Tp value_type;
typedef integral_constant type;
constexpr operator value_type() const noexcept { return value; }
constexpr value_type operator()() const noexcept { return value; }
};
template <class _Tp, _Tp __v>
constexpr const _Tp integral_constant<_Tp, __v>::value;
typedef integral_constant<bool, true> true_type;
typedef integral_constant<bool, false> false_type;
template <class _Tp>
struct is_default_constructible : public integral_constant<bool,
__is_constructible(_Tp)> {};
template <class _Tp>
inline constexpr bool is_default_constructible_v = __is_constructible(_Tp);
template <typename T>
void f()
requires is_default_constructible_v<T>
{
auto g = [](int x) requires is_default_constructible_v<T> {
};
}
```
There are separate `UnresolvedLookupExpr`'s attached to the `FunctionDecl` for
`f` and to the lambda-generated class's `operator()` and `CXXConversionDecl`.
I found `getTrailingReturnClause()` being used by
`RecursiveASTVisitor<T>::TraverseFunctionHelper()`.
