Fix more cases where DSE would optimize out too many stores
GCC5/6 do aggressive dead store elimination on memory passed to
placement-new. This resulted in the Heap::Object::prototype being a
nullptr. qml.pro already contained the -fno-lifetime-dse flag, but there
are other places where we ask the memory manager to allocate data.
This is temporary band-aid, and is already fixed in 5.8.
