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:
The generated code used to contain Prune statements that had boolean
connectives in their conditions. After this commit, all conditions
should have no boolean connective (LNot, LOr, LAnd) at top-level; that
is, prune conditions should be atomic.
The main motivation behind this change is that (a) frontends follow this
convention, and (b) Pulse assumes this convention.

Summary:
Currenlty the cost issue is printed at the first node of a function, which is usually the first
statment of the function. This may give a wrong impression that the cost of the statement is
changed.
This diff re-locate where to print issues with heuristics. Going backward from the first node
lines, it looks up a line satisfying,
1. A line should start with <fname> or should include " <fname>".
2. The <fname> found in 1 should be followed by a space, '<', '(', or end of line.

Summary:
This syntax
- is less confusing (according to several people who are not me);
objectively, there's less magic under the hood
- gives fine control over register number (because condition/action are separated)
- lets one compare values of different arguments of the same call
(e.g., one could have a transition that is taken only if two
arguments of a method call are equal)
