Marko Mäkelä 959ad2f30f MDEV-29612 ReadViewBase::snapshot() misses an optimization
ReadViewBase::snapshot(): In case m_low_limit_no==m_low_limit_id
and m_ids would include everything between that and m_up_limit_id,
set all fields to m_up_limit_id and clear m_ids, to speed up
changes_visible() and append().

rw_trx_hash_t::debug_iterator(): Add an assertion.
