Summary:
Add the `--source-files-cfg` option to emit CFGs as .dot files just as if one
had run with `--debug` to begin with. The usual `--source-files-filter`
applies. For example:
```
$ cd examples
$ infer -- clang -c hello.c
$ infer --continue -- javac Hello.java
$ infer --continue -- make -C c_hello
$ infer explore --source-files --source-files-cfg --source-files-filter ".*\.c$"
hello.c
c_hello/example.c
CFGs written in /home/jul/infer.fb/examples/infer-out/captured/*/icfg.dot

Summary:
`make clean` would fail calling `xcodebuild` to clean. It also calls `ant
clean`. Instead, do the cleaning ourselves by deleting the appropriate stuff so
that it's faster and more reliable.
Also clean the OCaml build before cleaning the tests as that's what more
important most of the time.
Also don't delete the man pages as part of `make clean` as they are checked in.
Also fix ant's Makefile so that the build points at the right .class files (the
path to the .class files was wrong so `make -C infer/tests/build_systems/ant`
would start `ant` for *each* file instead of once).

This diff does not copy callee's parameters on instantiating abstract
memories at call sites. Before this diff, it copied all reachable
values from callee's parameters including the parameters themselves.
However, they are local variables of callees and should not be copied
to callers.

Summary:
The `oenv` is an option.
This diff ensures that it is `Some` during the analysis and `None` when it is stored in a summary.
It could have been resolved with another type, e.g. `unit`, but an option was needed to avoid duplicating code that is generic up to some point.
The price to pay is a parametric type.

This diff extends the abstract domain to keep binary conditions on

Summary:
This will allow disjunctive analyzers to return sets of states as a
result instead of always returning one state. More precisely, this will
be needed for pulse when it becomes inter-procedural, if we take
summaries of functions to be disjunctive too (like, e.g., biabduction
does with several specs per function).

In ObjC there are no access modifiers. The strongest alternative is to put methods in the implementation but omit them from the interface declaration.

Summary:
It suppresses intended integer overflows that generate hash values or random numbers. For judging that the intention of integer overflow, it applies a heuristics: checking if traces of issues include a whitelisted words, e.g., "rand" or "seed".
While we would be able to suppress all integer overflows of unsigned integers since they have defined behaviors, we don't want to miss unintended integer overflows, e.g., that on unsigned index value.
