Refactoring of object bounds to make evaluated to original syncing
more explicit wasn't accounted for yet. This was a mistake in the most
recent refactor 1cbd0f5a85.
To fix this, add separate functions to account for `runtime.bb` which
is the data synced from the evalauted object to the original. In future
refactors, `runtime.bb` will be changed more, including a more helpful
name that reflects this purpose.
