test.d:
---
struct S {
   int i;
   alias i this;
}
void f(const S) {
}
void f(int) {
   assert(false); // line 8
}
void main() {
   f(S());
}
---

`rdmd test.d`:
---
core.exception.AssertError@test(8): Assertion failure
---

f(const S) should be called, not f(int). Conversion to const makes a better
match than  the implicit conversion of alias this:
