Example:
```cpp
// int __builtin_popcountg(...) noexcept;
int foo(int arg)
{
return __builtin_popcountg(arg); // Do not call c-style vararg functions clang-tidy[hicpp-vararg]
}
```
`__builtin_popcountg` actually takes a single argument, but its signature is ambiguous(internally interpreted as c-style va-arg according to clangd) to accept any integer type. Similarly, this applies to other builtins with ambiguous arguments.
