When performing a static downcast as part of a static_cast, make sure

that we're dealing with canonical types like the documentation say
(yay, CanQualType). Alas, this is another instance where using
getQualifiers() on a non-canonical QualType got us in trouble.

Good news: with this fix, Clang can now parse all of its own headers!
