Retrascope

The following issues should be fixed at "*BenchTest" test classes:

1. Substitute copy-pasted Javadoc header comments by relevant ones
2. ru.ispras.retrascope.engine.cfg.extractor.iface.VhdlCfgExtractorIfaceBenchTest: parameter getStatistics is never used at runTest method - refactoring is needed
3. There is a branch order for "if" operator that is used in the project. Following the rule, this form:
   

   if (cond) {
   ...
   } else {
   ..
   }
   

   
   is better than:
   

   if (!cond) {
   ...
   } else {
   ..
   }
   

   
   Take a look at "*BenchTest" classes to fix this rule's violations.
4. Fix "Local variable 'argPaths' is redundant" warning that appears while opening ru.ispras.retrascope.engine.cfg.transformer.gadd.VerilogCfgGaddBenchTest class in IntelliJ IDEA. This warning also appears at other "*BenchTest" classes too. Other warnings that are produced by IntelliJ IDEA are also worth to be fixed.
5. Having expressions like "!x.endsWith(y) && !x.endsWith(z) && !x.endsWith(w) && ..." you should rewrite them with single "!x.matches(..)" expression. Take a look at regular expressions in Java.
