Browse source 
size of TGBAs represented as BDDs by deleting unaccepting SCCs.

* src/eltlparse/eltlparse.yy: Remove a warning.
* src/tgba/tgbabddconcrete.cc, src/tgba/tgbabddconcrete.hh,
src/tgba/tgbabddcoredata.cc, src/tgba/tgbabddcoredata.hh: Add a
new function delete_unaccepting_scc in both classes.
* src/tgbatest/eltl2tgba.cc, src/tgbatest/spotlbtt.test: Use this
new function in LaCIM for ELTL and bench it.
* src/tgbatest/defs.in: Fix it.
* bench/ltl2tgba/algorithms, bench/ltl2tgba/defs.in: Add LaCIM for
ELTL in benchs.
