        Description

        `G1BlockOffsetTablePart::_object_can_span` is used to assert whether the entry for the first card is zero or not. This field tracks the `ContinuesHumongous` state of the underlying region.

        Instead of relying on `HeapRegion` to update this field, BOT can query the region type directly.
