You need to preserve the non-address-space qualifiers, the same way the code after the loop does.  Actually, I'd just recommend restructuring to use the existing code, something like:

```
if (T.getTypePtr()->isArrayType()) {
  getUnqualifiedArrayType()
} else {
  while (T.hasAddressSpace()) {
     [...]
  }
}
```
