[lsan] Make the report_objects flag more useful.

Print the list of leaked objects after each leak report. Previously we
printed only a joint list of all leaked objects. As a bonus, suppressed objects
are no longer reported.

[lsan] Remove the LSan-specific verbosity flag.
...
It conflicted with the verbosity flag we had in common flags. We don't need an
LSan-specific flag anyway.
Also, shift some logging levels and remove some unnecessary code.

[lsan] Introduce print_suppressions flag.
...
Introduce a flag to either always or never print matched suppressions.
Previously, matched suppressions were printed unconditionally if there were
unsuppressed leaks. Also, verbosity=1 no longer has the semantics of "always
print suppressions and summary".

source of live pointers. Useful for code which stores pointers in mapped memory.
