tgbatest: speed ltl2ta.test up!
Again instead of calling ltl2tgba dozen of times with different options for various formulas, this implements a single executable that reads formulas from a file, translate them using the different setups, and dump statistics for comparison. Valgrind now only has to be started once. * src/tgbatest/checkta.cc: New file. * src/tgbatest/Makefile.am: Use it. * src/tgbatest/ltl2ta.test: Rewrite using checkta. * src/tgbatest/ltl2tgba.cc: Remove a unused variable.
