V8 based memory analysis

Providing memory analysis tools for QML does not make too much sense right now since the results may not be accurate at all. The problem is that the real memory consumption heavily depends on the garbage collector that cannot always know how much memory a certain object really consumes (in C++ backend). Therefore, even large objects remain in memory even though they are not used any longer.

Implementing any special functionality in the QML engine for e.g. feeding the garbage collector more information is not worth the exercise right now since the planned switch to V8 will likely void all those changes. Therefore, we have to postpone the development of QML memory analysis tools at least until summer 2011.
