Simplify F(a)|F(b) as F(a|b). Add similar rule for G(a)&G(b).
* src/ltlvisit/basicreduce.cc (basic_reduce_visitor): Replace
the FG(a)|FG(b) == FG(a|b) rule by the above more generic one.
the FG(a)|FG(b) == F(Ga|Gb) rule by the above more generic one.
Add the dual rule for G(a)&G(b), as we had none (this one won't
improve anything in the translation, but it is more symmetric
this way). Also simplify some pointer checks.
