Darwin, Objective-C : Adjust objective-c symbol linkage with version.
Earlier linkers cannot handle publicly-visible (or linker-visible)
metadata, so we need to make the output of these conditional on version.
gcc/ChangeLog:
* config/darwin.c (darwin_globalize_label): Make a subset of
metadate symbols global.
(darwin_label_is_anonymous_local_objc_name): Make a subset of
metadata symbols linker-visible.
(darwin_override_options): Track more target OS versions, make
the next_runtime version track this (unless it's set to 0 for
GNU runtime).
gcc/objc/ChangeLog:
* objc-next-runtime-abi-02.c (FIXUP_NEEDED): Rename ...
(USE_FIXUP_BEFORE): ... to this.
(next_runtime_02_initialize): Likewise.
(next_runtime_abi_02_get_arg_type_list_base): Likewise.
(next_runtime_abi_02_build_objc_method_call): Likewise.
