my refactoring of builtins changed target-specific builtins to only be
registered when PCH wasn't being used.  We should always install (in BuiltinInfo)
information about target-specific builtins, but we shouldn't register any builtin
identifier infos.  This fixes the build of apps that use PCH and target specific
builtins together.
