If-Null return/break/... foldable to '?:'

Reports an if expression that checks variable being null or not right after initializing it that can be converted into an elvis operator in the initializer.

Example:

fun test(foo: Int?, bar: Int): Int {
    var i = foo
    if (i == null) {
        return bar
    }
    return i
}

The quick-fix converts the if expression with an initializer into an elvis expression:

fun test(foo: Int?, bar: Int): Int {
    var i = foo ?: return bar
    return i
}
