Subject: [PATCH] Further reduce the number of nodes cloned with getClonedNH,
 using merge instead. This reduces the number of nodes allocated, then
 immediately merged and DNE'd from 2193852 to 1298049.  unfortunately this
 only speeds DSA up by ~1.5s (of 53s), because it's spending most of its time
 waddling through the scalar map :(
