Fix relation query of equivalences.
When looking for relations between equivalencies, a typo was causing
the wrong bitmap to be checked. Effect was is missed them.
Plus don't dump blocks which don't exist.
* value-relation.cc (equiv_oracle::dump): Do not dump NULL blocks.
(relation_oracle::find_relation_block): Check correct bitmap.
(relation_oracle::dump): Do not dump NULL blocks.
