…lvm#171213) We're considering modifying the ObjC runtime's class_rw_t structure to remove the firstSubclass and nextSiblingClass fields in some cases. LLDB is currently reading those but not actually using them. Stop doing that to avoid issues if they are removed by the runtime. rdar://166084122 (cherry picked from commit 0c0ed39)
