Summary:
The property SkipAfterRemove already had a test, but not for
intra-procedural violations. This adds a test for that case.

Summary: add subdirectories so that we can run each java file against its own topl properties

Summary:
Old versions of sawja/javalib got the line numbers slightly wrong. The workaround was to do a regexp search in the source file for the right line.
My understanding is that this is no longer necessary. This diff removes it.

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.

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.
