We were generating getters and setters in the frontend, and then removing them if they were not needed
in the preanalysis. This diff adds a builtin getter that gets called if we are going to skip the function. That
means, if there was a getter written by the developers we still use that one rather than the builtin.
Code for setter and cleanup of preanalysis will come in a next diff.

Summary: public
Since we are only running the analysis on the Buck targets that are of type java_library or android_library, it may happen that the filtering gives an empty list of targets.
This diff does two things:
1) it filters out the empty strings `''` that can be returned when parsing the `buck query` command, and
2) skip the analysis when the list of targets to analyze is empty.
It also fixes the debug output for the list of targets to analyze, which was previously always printing the list of targets passed in the command line argument, which led for this issue to be unoticed even though it may have been there for a while already.

With this change it will be possible to instruct Buck to not analyze certain files whose names match
with the regex passed in input.
So for example if you want to skip the analysis of files containing `skip_me` on their names, then
the command:
infer --use-flavors --blacklist-regex ".*skip_me.*" -- buck build <target-name>
will do it, because the `.*skip_me.*` regex will match the desired rule.

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

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.
