Surely we can come up with some tougher overloading test cases. I noticed MSVC generates a warning when converting from '__unaligned T*' to 'T*' with this code:
```
extern "C" int puts(const char *);
void f(__unaligned int *p) {
  puts("unaligned");
}
void f(int *p) {
  puts("aligned");
}
void g(int *p) {
  puts("g");
}
int main() {
  int *p = 0;
  __unaligned int *q = 0;
  f(p);
  f(q);
  g(p);
  g(q); // C4090
}
```
