Option -v outputs a list of used suppressions. This only gives the nr of times a suppression was used. For a leak search, this only gives the nr of loss records that have been suppressed, but it does not give additional needed details to understand more precisely what has been suppressed (i.e. nr of blocks and nr of bytes). => Add in the tool interface update_extra_suppression_use and print_extra_suppression_info functions to allow the tool to record additioonal use statistics for a suppression. These statistics can be done depending on the error (and its data) which is suppressed. Use this in memcheck for the leak suppressions, to maintain and output the nr of blocks and bytes suppressed by a suppression during the last leak search. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13651
