Summary:
This change introduces a new binary, called `InferStatsAggregator`, that once invoked, aggregates
together all the stats generated by the single invocations of frontend/backend/reporting, that can
be used for performance measurements.

Summary:
Optimize attribute loading by caching all attributes read from file in
memory. This reduces io and allocation rate and raises memory usage.

Summary:
Reimplement command line options in preparation for uniformly passing
options from the top-level infer driver that invokes a build command
through the build system to the descendant infer processes.
All command line options of all executables are collected into Config,
and declared using a new CommandLineOption module that supports
maintining backward compatibility with the current command line
interface. Very few values representing command line options are
mutable now, as they are set once during parsing but are constant
thereafter. All ordering dependencies are contained within the
implementation of Config, and the implementation of Config is careful to
avoid unintended interactions and ordering dependencies between options.

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).

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.
