Equality check can be used instead of elvis for nullable boolean check

Reports cases when an equality check should be used instead of the elvis operator.

Example:

fun check(a: Boolean? == null) {
    if (a ?: false) throw IllegalStateException()
}

After the quick-fix is applied:

fun check(a: Boolean? == null) {
    if (a == true) throw IllegalStateException()
}
