As far as I understand the qualifiers here are only used to rebuild the type. 
Therefore I assumed I don't need to restore the original. I am now thinking of 
moving this down into `RebuildQualifiedType` that has similar code for handling 
qualifiers.

However, after enabling it for C++ in general I am getting some issues with 
deduction of templates with pointers that have address spaces in pointees. So I 
am investigating this further whether it's the right approach at all.
