Summary:
Results of AbsInt checkers are node id -> abstract state maps.
It's hard to compare/combine the results of multiple analyses if the node id types are different.
Needed for the upcoming improvements of the preanalysis.

Summary:
The case where the right hand side of the `Letderef` expression is an identifier was missing. With this diff, the following example is now working as expected:
class A {
public Object foo() {
return new Object();
}
}
class B extends A {
public Object foo() {
return null;
}
}
public class Test {
static Object bar(A a) {
return a.foo();
}
static void shoulReport() {
B b = new B();
bar(b).toString();
}
}

Summary:
As suggested in the discussion https://github.com/facebook/infer/issues/326 this pull request implements
```ocaml
get_overriden_method : Tenv.t -> Procname.java -> Procname.t
```
to get the method of a superclass that is being overridden by a specific java pname.
I thought of unit test this, but unfortunately I wasn't able to figure out how to create the proper context with OUnit2. Perhaps the easiest way to test this will be integration tests.
Feel free to reject the pull request if unit tests are mandatory (or for any other reason, of course).
Closes https://github.com/facebook/infer/pull/341

Summary:Make node ids be `private int` to make sure we don't mix them with random

Summary:This wasn't used anywhere. Frontends that wish to do something like goto can
just set the targets of the goto as successors of the current node, no need for
a special instruction to do that.

Summary:public
When a conditional is the last instruction, there will be a join node leading directly to the exit node.
Some instructions, such as nullification of dead variables, and abstraction, are added to the control flow graph automatically. But, join nodes cannot contain instructions. So when a procedure ends with a conditional, there might be no place to store these instructions.
This diff adds one extra node between the join and the exit node in that situation.

Eliminate the use of the -open Utils command line option passed to the compiler in favor of `open! Utils` in each source file. While slightly convenient, this option causes more headaches than it is worth with other tools e.g. merlin.
