Small cleanup in class name resolution of compiler

 * The fetch_type and check_ns_name parameters of
   zend_resolve_class_name were unused and are now removed.
 * ZEND_FETCH_CLASS_GLOBAL is no longer used (no code actually
   checking for it).
 * The checks for usage of "namespace" as class name were
   unnecessary as that situation can't occur anyways.

   will not free interned strings.
