[Bug c/13038] no diagnostic for null pointer misuse

I don't think an implementation may extend the meaning of an _integer_ constant 
expression.  IMHO 6.6#10 only says that it may accept other _forms_ of constant 
expressions, beyond the forms already defined by the standard (ie. integer, 
arithmetic and address constants).
