The lto people were trying to get all the types for builtins to come out correctly in the debugging information, which is a nobel goal, and I would love to see that work, but there are a few ports that cause major problems with trying to do that.  Darwin is one such port.  This fixes the i386 issues, and fixes some of problems on ppc, but apparently not all of them.  If someone can point out the remaining problem on ppc, I'll fix it, I just need a pointer on what data is being access, see the PR for details.

Richard said it looked to to check in now (instead of waiting til stage1).

	PR target/47822
	* config/darwin-protos.h (darwin_init_cfstring_builtins): Return a
	tree so we can get save the type.
	* config/i386/darwin.h (SUBTARGET_INIT_BUILTINS): Reserve builtin slot
	for CFString instead of trying to use past the end of the builtins.
	* config/i386/i386.c (IX86_BUILTIN_CFSTRING): Likewise.
	* config/rs6000/rs6000-builtin.def (RS6000_BUILTIN_CFSTRING): Likewise.
	* config/rs6000/darwin.h (SUBTARGET_INIT_BUILTINS): Likewise.
	* config/darwin.c (DARWIN_BUILTIN_CFSTRINGMAKECONSTANTSTRING):
	Rename to darwin_builtin_cfstring.
	(darwin_init_cfstring_builtins): Return the built type.
