It's a fallout when Denis moved the code for rematerialization to another
point.  While doing spills itself nothing is really rematerialized.
Instead simple remat webs are later optimized again, to effectively form a
rematerializing load instead of a load/store pair.  The counting wasn't
adjusted, though.
