Have ZeroLiveBytesForLargeObject process all the regions of a large object.

When executing `RegionSpace::ZeroLiveBytesForLargeObject(obj)`, in
addition to zero-ing the live bytes count of the large region starting
at address `obj`, also zero the live bytes count of the associated
large tail regions.

This addresses an issue with Sticky-Bit (Generational) CC collection,
where an assertion in RegionSpace::ClearFromSpace could fail when
processing a large unevac from-space region whose allocated bytes were
all live.

Test: ART run-tests & gtests, libcore tests, JDWP tests (host & device)
