Summary:
Makes sure that topl summaries don't repeat. Previously this happened
when two posts led to the same summary when procedure-local variables
were killed. Such repeated summaries quickly lead to exponential
explosion. (For example, the added test -- `ManyLoops.java` -- didn't
finish in any reasonable time.)

traces.

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:
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)

Summary:
This adds a violation of baos.topl found in github/seata/seata. However,
it is not a bug (see comment in commit).

If data comes from an outer OutputStream, then this outer OutputStream
needs to be flushed before getting the byte array.
