work around some g++-7.3 issues

Browse source 
* spot/twaalgos/langmap.cc, spot/ltsmin/ltsmin.cc: Add asserts to hide
spurious "potential null pointer dereference" messages.
* spot/twaalgos/tau03opt.cc (color_ref): Initialize pc to nullptr
even when is_cyan is true so that valgrind does not report pc being
used uninitialized in is_white().
