Ah, yea, I think I need to fix this a different way.
The case where this happens is:
```c++
void fn(float x[2]);
void call(float Arr[2]) {
fn(Arr);
}
```
In the CallExpr to fn, the argument is an lvalue DeclRefExpr to the ParmVar.
I think the right way to do this is to insert an ImplicitCastExpr for
CK_HLSLArrayRValue or CK_LValueToRValue.
