* For all tools and the core, don't show statistics when -v is in effect. Instead, try to restrict -v to mostly user-useful stuff. * A new flag --stats=no|yes [no] produces statistics output instead. * Fix longstanding problem in that Memcheck's leak checker ran after the core's error manager module shut down, thereby not showing use counts of leak suppressions. This fixes #186790. * As a consequence, the leak checker text output of Memcheck has changed a bit -- leak check is done before the final error summary is done (much more logical), and the output has been tidied up a bit. * Helgrind, Drd and Ptrcheck now also print "For counts of detected and suppressed errors, rerun with: -v", which makes them consistent with Memcheck in this regard. These are filtered out by the regtest filter scripts. For all tools except Memcheck, the regtests are unchanged. On Memcheck regtests still fail due to rearrangements of the leak checker output. This will be fixed by a followup commit. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10746
