Summary:
`AnalyzerNodesBasicCost` is just mapping instructions to abstract costs, it doesn't need to use AI.
Also it was keeping a map (node -> cost) for each node, this is completely removed.

Summary:
- There is no need to use AI to compute a dot product: let's just fold over all nodes, but still do it in order (using the WTO) to report at the right place
- The previous version was computing a dot product on nodes for each node, which was quadratic, the new version is linear
- Report only once, the first time the threshold is reached (if in a loop, report at the loop head)

Summary:
Add an option to specify some classes that we really want to warn about
with the liveness checker, even when they appear used because of the
implicit destructor call inserted by the compiler.

Summary:
The purpose these serve is unclear to me. From the comment I *think*
they were used to hint to the biabduction backend that smart pointers
are just pointers. That said, The tests still mostly pass even without
that (just a few `weak_ptr` tests changed from `NULL_DEREFERENCE` to
`Bad_footprint`).
Moreover, this extra dereference was added unreliably. For instance,
this piece of code:
```
auto x = std::make_unique<X>(some_X);
```
would either get the extra dereference or not depending on which headers
were picked for the C++ stdlib.
The extra dereference was tripping up the liveness checker (see later in
the stack), and probably most checkers too.

Summary:
Make sure the functions in jClasspath.ml are tail rec so they don't blow the stack on large inputs.
Do that by tightening the try/with to not include recursive calls.

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

This diff does not copy callee's parameters on instantiating abstract

However, they are local variables of callees and should not be copied
