Add a new corpus_diff::has_net_changes() entry point

Browse Source 
This entry point is to test if there are still ABI changes between two
corpora after applying suppression specifications.

	* include/abg-comparison.h (corpus_diff::has_net_changes): Declare
	new member function.
	* src/abg-comparison.cc (corpus_diff::has_net_changes): Define it.
