after the simulation-reduction.

Report from Tomáš Babiak <xbabiak@fi.muni.cz>.

* src/tgbaalgos/neverclaim.hh (never_claim_reachable): Take
a tgba as input.
* src/tgbaalgos/neverclaim.cc (never_claim_bfs): Call
state_is_accepting() only if this tgba turns out to be
a tgba_sba_proxy.  Otherwise check the acceptance of one
outgoing transition as we do in dotty_bfs since 2011-03-05.
* src/tgbatest/ltl2tgba.cc: Do not redegeneralize before
calling never_claim_reachable() if we know the automaton is
degeneralized already.
* src/tgbatest/ltl2tgba.test: Add a test case.
