Avoid adding auxiliary 'jimple' variables to the list of possible conflicts.

[barbosamaatheus]

Currently in the implementation of Overriding Assignment, when the 'jimple' creates additional auxiliary variables, these variables are added to the list of possible conflicts which generates a greater effort when it comes to flicting the real conflicts in this list and this consequently has an impact on performance . Avoiding adding these variables is a possible solution.

Example:

public class Sample{

    public void m() {
        int x = foo() + bar(); // LEFT    x = $stack2 + $stack3 // Jimple
        x = x + qux();         // RIGHT   x = x + $stack4 // Jimple
    }
    ...
}

In this example, $stack2, $stack3 and $stack4 are added to the list when, in fact, it was only necessary to add x
