Mike Ash 70354af2b5 [Runtime] Avoid operator new/delete in ConcurrentReadableArray. ...

The callbacks made in ImageInspectionMachO.cpp are called in a dangerous context, with the dyld and ObjC runtime locks held. C++ allows programs to overload the global operator new/delete, and there's no guarantee that those overloads behave. Ideally, we'd avoid them entirely, but that's a bigger job. For now, avoid the worst trouble by avoiding STL and new/delete in these callbacks. That use came from ConcurrentReadableArray's free list, so we switch that from a std::vector to a linked list.
