Not TREE_ADDRESSABLE var _OBJC_CLASS_REFERENCES_0
Not TREE_ADDRESSABLE var _OBJC_SELECTOR_REFERENCES_0
Not TREE_ADDRESSABLE var _OBJC_SELECTOR_REFERENCES_1
read-only var _OBJC_CLASS_REFERENCES_0
read-only var _OBJC_SELECTOR_REFERENCES_0
read-only var _OBJC_SELECTOR_REFERENCES_1

So it's indeed ipa-reference that promotes the static vars and CCP that
propagates the initializer.  I see nothing wrong here, so the ObjC frontend
must do something behind the middle-ends back.

If you look at the final assembler code, is there anything modifying
the contents of those three variables?
