libstdc++: Fix GDB Xmethod for std::shared_ptr::use_count() [PR109064]
libstdc++-v3/ChangeLog:
PR libstdc++/109064
* python/libstdcxx/v6/xmethods.py (SharedPtrUseCountWorker):
Remove self-recursion in __init__. Add missing _supports.
* testsuite/libstdc++-xmethods/shared_ptr.cc: Check use_count()
and unique().
