Summary:
This diff does refactoring for the following diff.
* Define Mangled.return_param and Mangled.is_return_param and use it instead of
Ident.name_return_param.
* Share common code from objc_setter and objc_getter
* Move struct_copy to CStructUtils.ml

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:
Emit the crucial parts of Pulse summaries as json to enable
post-processing by external tools. Stop somewhat arbitrarily at some
datatypes that are just emitted as "opaque" values.
For example:
```
$ infer debug --procedures --procedures-summary-json --select 0
[[["pulse",[["ContinueProgram",{"post":{"heap":[["v3",[[["Dereference"],["v4","_"]]]],["v7",[[["Dereference"],["v3","_"]]]]],"stack":[[["ProgramVar",{"plain":"return","mangled":null}],["v7","_"]]],"attrs":"_"},"pre":{"heap":[],"stack":[],"attrs":"_"},"skipped_calls":"_","path_condition":"_"}],["ContinueProgram",{"post":{"heap":[["v3",[[["Dereference"],["v4","_"]]]],["v8",[[["Dereference"],["v3","_"]]]]],"stack":[[["ProgramVar",{"plain":"return","mangled":null}],["v8","_"]]],"attrs":"_"},"pre":{"heap":[],"stack":[],"attrs":"_"},"skipped_calls":"_","path_condition":"_"}]]]]]

Summary:
This preanalysis in general aims to create specialized clones of methods that have blocks as arguments and that are called with concrete closures, and then call these clone methods instead of the original ones.
One complication is what happens with the captured variables in the closure. What we do is we add them to the formals of the cloned method and passed them through to the concrete blocks.
We do this transformation in two steps:
1. Go through all the callers of methods with blocks as parameters, and create the clone methods. In this preanalysis we only create the attributes for the new method, not the code. We also update the call instructions in the callers to represent a call to the cloned method with updated arguments: we don't need to pass closures arguments anymore, we instead pass the captured variables as new arguments.
2. We add the corresponding code to the newly created clones: this means swapping the call to the block variable with a call to the corresponding block. Moreover, we add some of the new formals (that correspond to the captured variables) to the arguments of the call.
This diff implements step 1 of the analysis. The next diff D23216021 implements step 2.

Summary:
Found the dead code with the script in the next commit, iteratively until no
warnings remained.
Methodology:
1. I kept pretty-printers for values, which can be useful to use from infer's REPL (or
when printf-debugging infer in general)
2. I kept functions that formed some consistent API (but not often, so YMMV), for instance if it looked like `Set.S`, or if it provides utility functions for stuff in development (mostly the procname dispatcher functions)
3. I tried not to lose comments associated with values no longer exported: if the value is commented in the .mli and not the .ml, I moved the comment
4. Some comments needed updating (not claiming I caught all of those)
5. Sometimes I rewrote the comments a bit when I noticed mis-attached comments

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.
