It seems that `getCanonicalTypeUnqualified` does not strip qualifiers from the
canonical type. I guess "Unqualified" here just means the method does not
include local qualifiers, unlike QualType::getCanonicalType.
Thus, in the case of `using cbase = const base;`, `getCanonicalTypeUnqualified`
will return the canonical type of `cbase` as is, which is `const base`, a
const-qualified type.
