In HLSL `decltype(half) == decltype(float)` when 16-bit types are not enabled. Today that is not the case. When 16-bit types are disabled today `half` is a distinct 32-bit type. This causes challenges in overload resolution. With 16-bit types disabled the following case should have an exact match:
```c++
float fn(float f);
half call(half x)
{
return fn(x);
}
```
### Acceptance Criteria
A test case demonstrating correct overload resolution for the case above.
