Clang seems not to recognize that a friend function is redeclared, if it has "requires".
```
#include <stddef.h>
template<size_t i>
struct A
{
friend constexpr inline void b(A<i>) requires(i == 3)
{}
};
constexpr void b(A<3>);
void Do()
{
::b(A<3>());
}
```
Emits:
```
"Do()":
jmp "b(A<3ul>)"
```
This results in an unresolvable function reference at link time.
GCC seems to behave the same way, however MSVC gets it right.
If the "requires" is removed, everything works fine.
