Thanks.  Can I do as the following?
Note that I am passing QualifierCollector to getUnqualifiedArrayType, which has Qualifiers as the second argument.
 Also,  TypeNode = T.getTypePtr(); after I is unqualified.

 QualifierCollector Quals;
  const Type *TypeNode;
  if (T.getTypePtr()->isArrayType()) {
    T = getUnqualifiedArrayType(T, Quals);
    TypeNode = T.getTypePtr();
  } else {
  while (T.hasAddressSpace()) {
  ....
