New API function (get_expl_freed_bytes_since_gc)

Note: this function could be used in test_cpp to check that the proper
operator delete is called.

* include/gc.h (GC_get_expl_freed_bytes_since_gc): New function
prototype.
* mallocx.c (GC_get_expl_freed_bytes_since_gc): New function definition
(which returns GC_bytes_freed).
