2d1cb0ddcd zlktree: replace std::vector<bool> by bitvect in ACD
On the example from previous patch, the number of instruction fetches
goes from 18490399159 down to 18248898077.

* spot/twaalgos/zlktree.cc, spot/twaalgos/zlktree.hh (acd): Use
bitvect instead of std::vector<bool> in nodes.  This make is easier to
update an edge of a bitvector shared by multiple nodes set after
pruning non-maximal sets from an SCC.  Also compute the set of states
hit by the edges at the very end, once all nodes are known.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh,
spot/twaalgos/genem.cc, spot/twaalgos/genem.hh: Adjust to work with

issue #476.

Running
PREFIXCMD='valgrind --tool=callgrind' ./run python3 -c \
"import spot; spot.acd_transform(spot.automaton('syntcomp_91.hoa'))"
went from 65139436227 instruction fetches down to 18490399159.
