CDB: Fix STL debugger helpers for MSVC2012 beta.

In MSVC2012, more bases classes for std::string
and containers were introduced whereas std::pair_base
was removed compared to MSVC2010.

Add a findMember() function to be able to skip base
classes when looking for a certain member to finally
fix this issue.
Introduce SymbolGroupValue::parent()/childCount()
and simplify the helpers using it.
