Summary: public
Refactor compute_results_to_parent to call collect_res_trans directly there.
So the job of PriorityNode.compute_results_to_parent is the following:
Given list of [res_trans_1; res_trans_2; ... ; res_trans_n],
1. Connect nodes linearly (ie. res_trans_1 with res_trans_2, res_trans_2 with res_trans_3) etc.
If res_trans_k has no nodes, try connecting res_trans_k-1 with res_trans_k+1 (this is what collect_res_trans always did)
2. Collect all ids, instrs and exps into one res_trans
3. Create node if needed and put there same ids and instrs as usual.
4. Connect new node with existing ones
4. Return new node structrue with exps = []
This will make function usable in more places so we don't have to create nodes over and over again

Not finding C++ method in decl map was considered impossible to happen.
It turns out it can happen because ast exporter wasn't exporting template
instantiations.
So instead, pick a default when method decl is not found. This will be right in
most cases and will allow us to analyze rest of the function without crashing

Summary: public
Using clang's method resolution. This means that, in method calls, clang gives you a pointer to the declaration of the method.
In some cases though, clang doesn't find the right method. For example, when it finds a method in a category, we
need to make it into a method in the corresponding class, because that's how we treat categories in Infer. Moreover,
when it finds a method in a protocol, that is not useful for us, since the implementation will be in some class. Finally,
sometimes the call is on an object of type id, in which case clang doesn't know what is the correct declaration. In
those cases, we fall back to what we were doing before of approximating the method resolution. We also refactor
some of the code.

With this change, it will be possible to pass to InferAnalyze a list of folders to be
searched for spec files, through a file containing those paths, separated by the newline
character.
For example, if there's a `PathList.txt` file containing
/path/to/specs/folder1
/path/to/specs/folder2
/path/to/specs/folder3
Then invoking `infer --specs-dir-list-file PathList.txt [--other_args, ...] -- <build_cmd>`
will instruct the analyzer to lookup to those three folders whenever it searches for specs.
It's important to note that since the analyzer runs in parallel from different locations, it's necessary to pass **absolute** paths, or the analyzer will fail with an error.
