74eaba4de2 Merge the Mem.r value into the MemValue union as Mem.u.r. Hence, a Mem can 
now store an integer or a real but not both at the same time.  Strings are
still stored in a separate element Mem.z, for now.

7ea31ccb01 Since numeric affinity is the most common case, check it first. Interchange
