JDK-8206457 - Code paths from oop_iterate() must use barrier-free access
Description
InstanceMirrorKlass::oop_size can be used heavily by GC. It delegates to java_lang_Class::oop_size_raw, which is a trivial method that unfortunately isn't inlined. Inlining is a net win on binary size and reduces time spent executing InstanceMirrorKlass::oop_size by a third when profiling.
