Use the new object creation profiler in qqmlvme

Use the new object creation profiler in qqmlvme

There are 3 ways to create objects: "Simple", "Cpp" and "Qml". This
patch starts a new profiler whenever a new object is created.
It's assumed that everything the interpreter main loop does between
two creation instructions is related to the object just created.
The componentComplete calls are profiled by restoring saved states
of the profilers used during the creation of the respective objects.
