Summary:
Before this diff, TOPL had 3 implementations:
1. a post-processing of biabduction summaries
2. a post-processing of pulse summaries
3. a deep embedding in pulse
1 and 2 additionally require instrumenting SIL to generate monitors for
the TOPL properties. 3 is faster than both 1 and 2, by a good lot, and
doesn't require instrumenting the SIL code. Thus, delete 1 and 2!
Also harmonise the CLI so that TOPL is activated by --topl, which
actives it as a checker, like other analyses.

Summary:
A "large step" is a call, and it is "trivial" if it does not affect the
automaton state; i.e., if it is irrelevant to the property being
tracked.

Summary:
Now one can use the pattern #ArrayWrite(A,I) to match on a write at
index I in array A. This only works in the Pulse variant of Topl (not in
the one based on SIL instrumentation).
