Function mmtk::util::metadata::vo_bit::is_vo_bit_set_unsafe

pub(crate) unsafe fn is_vo_bit_set_unsafe(
    address: Address
) -> Option<ObjectReference>

Check if an address can be turned directly into an object reference using the VO bit. If so, return Some(object). Otherwise return None. The caller needs to ensure the side metadata for the VO bit for the object is accessed by only one thread.

The address must be word-aligned.
