isl_map_print: use consistent names on all disjuncts
isl_map_print: use consistent names on all disjuncts

Although the dimension specifications of the basic maps in a map
are compatible with that of the map itself, the names need not
be the same.  Use the dimension specification of the map itself
whenever we need to print out a name to ensure the names are
consistent.
