Summary:
Rename symbols in test files so they are not duplicated and files can be analyzed together without affecting analysis results.
Fix some compilation errors, where files could be analyzed but would fail direct compilation.
Add Makefile mimicking the same analysis parameters used for the existing tests.

Summary:
Adding a new mode linters. Now if the analyzer is linters, we do the linters and don't translate,
then, if the analyzer is Infer, we do the translation and the backend and not the linters checks, and the
default is that we do capture, backend and lint checks.
Made the tests separated, which saves time and also shows that the linters mode works.

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.

Instead of using location of init_stmt, use location of variable when translating initialization.
Most of the time it change anything with some exceptions:
// example1 - C/C++/objC
int x = // now: assignment happens in this line
3; // past: assignment happens in this line
// example2: valid in C++11 only
struct X {
int x = 0; // now: one assignment here
int y = 2; // now: one assigmnent here

Summary:public
Improved/simplified framework for fronend checkers.
Now we have a unique hook from cTrans to run checkers on statements and a unique
hook from cFrontent to run checkers on declarations.
So now when adding a checker we don't have to modify cTrans/cFrontend.
Moreover made more sistematic the way checkers are invoked. This simplify the definition
of checkers and the way we use them.
Code is now simpler.

Summary:
public To deal with ObjC nullability and give meaningful error
messages, we introduced the ObjC_NULL attribute in the symbolic execution to
mean that the object carrying the attribute is null because it was the result
of a method call from a null object. However, one cannot add attributes to null,
so we had to delay nullifying the object in order to have the attribute until we
can assign it to a program variable. However, if the temp variable was used in a condition,
we were not taking into account that its meaning is null. This diff addresses that and fixes
many FPs that we have encounter.
