Hmm, this makes the new builtin_type sound more like the target language
pointer (C's void*) rather than the target architectures address.  That
would suggest the need for a different name and a comment explaining why
it isn't CORE_ADDR.

Is the list of cases:

	o	CORE_ADDR
		builtin_type_CORE_ADDR?

	o	object file addr
		builtin_type_bfd_addr

	o	language addr
		builtin_type_C_pointer?
		hmm, GDB's current schemea would
		make it just builtin_type_pointer.

complete?  If we added all of them you can then just pick and choose :-)

Stan,
now you're the stylistic expert, thoughts?

	enjoy,

PS: I like your move to add builtin_type_*.  I think this is going to
finally cleanup/fix another of GDB's confusions.
