memops: kill dead loads before phi-node conversion
During load simplification it may happen that a load is unused
but if this fact is ignored and the usual conversion to a phi-node
is made, then this value may seem to be needed and can't anymore
be simplified away.
Fix this by removing dead loads during load simplification.
