Class transformSwitchToIf

Transforms a switch statement into an if statement.

This means that code like this:

	int num = 1, a;

	switch (num) {
	    case 1:
         a = 10;
	   default:
	   	    a = 30;
	        break;
	   case 2:
	       a = 20;
	       break;
    case 3 ... 7:
        a = 30;
	}
Copy

Will be transformed into:

 int num = 1, a;

 if (num == 1)
     goto case_1;
 else if (num == 2)
     goto case_2;
 else if (num >= 3 && num <= 7)
      goto case_3_7;
 else
      goto case_default;

 case_1:
     a = 10;
 case_default:
     a = 80;
     goto switch_exit;
 case_2:
     a = 20;
     goto switch_exit;
 case_3_7:
     a = 30;

 switch_exit:
 ;
