TypePrinter should not ignore IndexTypeCVRQualifiers on constant-sized arrays 

C99 array parameters can have index-type CVR qualifiers, and the TypePrinter
should print them when present (and we were not for constant-sized arrays).
Otherwise, we'd drop the restrict in:

  int foo(int a[restrict static 3]) { ... }
