This patch replaces the decl_cloned_function_p function call with simpler macro 
uses.  As only cdtors are cloned, we can use IDENTIFIER_CDTOR_P to check.

In the process I discovered the documentation had bitrotted -- we were giving 
non-function_decls to the predicate, sometimes intentionally (template_decls), 
and sometimes unintentionally (record_types).  The new semantics are we can give 
  any _decl to the predicate and only function_decls to the accessor.  The 
change in pt.d is because at namespace scope, we chain record_types (&enums & 
unions) on the chain list.  Previously that was harmless but now causes the 
predicate to assert.

Applying to trunk.
