Oilpan: improve handling of ASan contiguous container annotations.
Follow up r190347 and support the retirement of contiguous container
annotations for 'non-inline' heap vector backing stores.
In order to handle the tracing of heap vector backing stores identified
conservatively via the stack or other roots without overflowing such
annotations, the tracing of these will implicitly widen the annotation
to apply to the entire backing store allocation.
