'if' statement with identical branches

Reports if statements in which common parts can be extracted from the branches.

These common parts are independent from the condition and make if statements harder to understand.

Example:

if (x > 12) {
  doSomethingBefore();
  doSomethingDifferent1();
  doSomethingAfter();
} else {
  doSomethingBefore();
  doSomethingDifferent2();
  doSomethingAfter();
}

After the quick-fix is applied:

doSomethingBefore();
if (x > 12) {
  doSomethingDifferent1();
} else {
  doSomethingDifferent2();
}
doSomethingAfter();

Updated in 2018.1
