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:
Report errors found by running Topl on top of Pulse, when using
--topl-pulse. Topl tests now run on top of Pulse.

Summary:
The old --topl-only is now --topl-biabd-only, and there's also
--topl-pulse-only. This is WIP: the latter runs pulse, but it doesn't yet
extract Topl errors from pulse summaries. (The citv part of pulse path
conditions appears to have the necessary information.)

Summary:
This seems to make sense as it's a separate analysis (that depends on
biabduction). This introduces unpleasant `|| is_checker_enabled TOPL`
whenever we try to figure out if biabduction will run. I think this is a
more general problem that deserves a more general solution to express
the fact that checkers can depend on others, so that, eg,
`is_checker_enabled Purity` is true when we pass `--loop-hoisting`. Will
address in another diff.

Summary:
The test shows what that TOPL can express, in addition to bugs,
efficiency properties. However, there seems to be an underlying problem
in biabdaction that prevents this particular problem from being caught.
