[topl] Bugfix in matching constructor names. Summary: The regexp was wrong. Reviewed By: ngorogiannis Differential Revision: D19035490 fbshipit-source-id: c91097f45 5 years ago			`prefix "Scanner"`
[topl] Generate simpler monitor for deterministic states. Summary: This is an optimization. We ask the user to tell us which states are nondeterministic, and we generate code that handle nondeterminism only for those states. It is common for only one state per TOPL property to be nondeterministic. This speeds up the biabduction-analysis of the monitor by a factor of ~10. But, using the monitor is only a little faster.

[topl] Support side conditions for transitions. Summary: In addition to state1 -> state2: pattern one can now also write state1 -> state2: pattern if condition where "condition" is some conjunction of comparisons (==,<,>) that involve variables bound by "pattern", registers of the automaton, and constants.
