The big one:
- stop using polymorphic `<>`, `<`, `>`, ..
- add `<>` to `PolyVariantEqual` escape hatch now that `<>` is as taboo as `=`
- Interestingly, there were a lot of uses of `Z.(x < y)`, which although
they seem to use `Z.lt` actually used polymorphic comparison. The actual
comparison infix operators of `Z` are cleverly hidden in `Z.Compare`
instead, which makes them impractical to use...

The ProcLocker uses files as locks and relies on the guarantees of the `Unix.open_file` function when using `O_CREAT` and `O_EXCL` simultaneously.
- `setup`: creates a directory for the lock files inside `infe-out` and deletes its content if it already existed.
- `clean`: does nothing for now. Any file locks that may have been left unlocked are removed by the `setup` in the next run. This way the user can see what locks were taken if the program crashes.
- `lock_exn`: try to lock the `Procname` and if it can't releases all the locks that is currently holding.
- `unlock`: removes the corresponding file.

This also prints the CFGs *after* pre-analysis for individual procedures
in infer-out/captured/<filename>/<proc>.dot. One can also look up the
CFGs before pre-analysis in infer-out/captured/proc_cfgs_frontend.dot.
Context: I want to add a pre-analysis that needs to look at proc
attributes inter-procedurally. For this to make sense it has to happen
*after* all of capture, and before analysis.
Thus, this diff brings back the lazy running of the pre-analysis like in
D15803492, except that we still make sure to run the pre-analyses
systematically regardless of the checkers being run by running the
pre-analysis from ondemand.ml. Also we don't need to re-introduce the
"did_preanalysis" proc attribute for the same reason that the
pre-analysis is now run once and for all by ondemand.ml (instead of each
individual checker back in the days).
This has the benefit of running the pre-analysis only when needed, and
the drawback that several concurrent processes analysing the same proc
descs will duplicate work. Since pre-analyses are supposed to be very
fast I assume that neither is a big deal. If they become more expensive
then the benefit gets bigger and the drawback is just the same as with
regular analyses.

Summary:
Introduce a new experimental checker (`--impurity`) that detects
impurity information, tracking which parameters and global variables
of a function are modified. The checker relies on Pulse to detect how
the state changes: it traverses the pre and post pairs starting from
the parameter/global variable and finds where the pre and post heaps
diverge. At diversion points, we expect to see WrittenTo/Invalid attributes
containing a trace of how the address was modified. We use these to
construct the trace of impurity.
This checker is a complement to the purity checker that exists mainly
for Java (and used for cost and loop-hoisting analyses). The aim of
this new experimental checker is to rely on Pulse's precise
memory treatment and come up with a more precise im(purity)
analysis. To distinguish the two checkers, we introduce a new issue
type `IMPURE_FUNCTION` that reports when a function is impure, rather
than when it is pure (as in the purity checker).
TODO:
- improve the analysis to rely on impurity information of external
library calls. Currently, all library calls are assumed to be nops,
hence pure.
- de-entangle Pulse reporting from analysis.

- When the daemon is running, read-only access is *not* enforced for other processes. This makes starting and stopping the daemon during Infer execution easier and more robust. In WAL mode this should not have any effect on performance.

Summary:
Summary.ml defines both a bunch of types and how to use them and a
mechanism to save and store summaries on disk while maintaining a
complex in-memory cache of what's on disk. Make the distinction clear.

Summary:
Fixes#1126
Different checks contain some ad hoc places that look at this param, but there is no systematic way to suppress this.
The centralized place that is filtering results is `reporting.ml`.
Note that this diff does not remove other usages, because they do more than mere filtering results.

Summary:
Move the logic that is general to any call graph from SyntacticCallGraph.ml into CallGraph.ml
This will allow the call graph logic to be re-used in a later diff

Summary:
The domain supported path sensitivity wrt to a specific boolean guard `Branch.unlikely`. This isn't used in actual code, so remove it.
Also
- add an .mli to the domain;
- unabbreviate domain name to match analyser name;
- use Payload.read instead of calling Ondemand directly;
- adjust tests.
