Add check that gc_cpp operator delete is called (test_cpp)

Browse Source 
Issue #195 (bdwgc).

* tests/test_cpp.cc (GC_CHECKED_DELETE): New macro.
* tests/test_cpp.cc (main): Use GC_CHECKED_DELETE() instead of operator
delete (where it is expected that the operator defined in gc_cpp.c/h
is called).
