<pre>
    This ICE seems to be triggered when using ^^T::template operator(); inside a requires expression (i.e., concept constraint).
Other uses like ^^T::operator(); compile fine.

**Reproducer:**
```cpp
template<typename T>
concept has_tmpl_call = requires { ^^T::template operator(); };

constexpr auto test0 = [](auto& p_self, double) -> int { return 42; };
static_assert(has_tmpl_call<decltype(test0)>);

int main() {}
```
**Compile command:**
```bash
clang++ -std=c++26 -freflection -fparameter-reflection -freflection-latest -stdlib=libc++ -O0 <source>
```
