Remove unused output files

Remove the binary trace output file and the automated copy of the
input script file because the new traceR does not need them anymore.
Remove counters from DO_CHILDREN in memory.c

Remove the counters from the DO_CHILDREN macro in memory.c and
also the associated outputs. These counters were supposed to count
unused structures, but the DO_CHILDREN macro is the wrong place
to do this as it is used multiple times in the garbage collector
to iterate over all in-memory data structures, so in a single GC
run the same counters could be incremented multiple times for the
same object.
