ltlsynt implement polarity and gequiv after decomposition too

Browse source 
* bin/ltlsynt.cc: Also simplify subformulas using polarity and global
equivalence.  Add support for --polarity=before-decompose and
--global-equiv=before-decompose to restablish the previous behavior.
* spot/tl/apcollect.hh,
spot/tl/apcollect.cc (realizability_simplifier::merge_mapping): New
method.
* tests/core/ltlsynt.test: Add new test cases.
