Summary:
This havocs event data, so that biabduction doesn't try to
track what was the last event processed by the monitor
(which is redundant as long as the state of the monitor
is tracked).

Summary:
Don't instrument SIL when we can determine statically that
biabduction symexec would be a no-op.

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.

Summary:
The synthetic methods from `topl.Property` are now nonempty: they
simulate a nondeterministic automaton.

Summary:
Instrument SIL according to TOPL properties. Roughly, the
instrumentation is a set of calls into procedures that simulate a
nondeterministic automaton. For now, those procedures are NOP dummies.

Summary:
TOPL properties are essentially automata, which specify a bad pattern.
This commit is just a parser for them.
