* src/ltlast/atomic_prop.cc, src/ltlast/automatop.cc, src/ltlast/binop.cc, src/ltlast/bunop.cc, src/ltlast/multop.cc, src/ltlast/unop.cc: Do not look for a key and then insert the (key,value) on failure. Simply insert (key,0), and replace 0 by value on failure. This replaces two map lookups by one.
