TARGET_VALID_POINTER_MODE unused?

Ok, there are two issues it seems.  First it is used in target.def:
/* True if MODE is valid for a pointer in __attribute__((mode("MODE"))).  */
DEFHOOK
(valid_pointer_mode,
 "",
 bool, (enum machine_mode mode),
 default_valid_pointer_mode)

But the other issue is that the default
default_addr_space_pointer_mode does not use it which means it is
unused really.  I think we should only have one or the other hook
really.
