Negated boolean expression can be simplified

Reports negated boolean expressions that can be simplified.

The quick-fix simplifies the boolean expression.

Example:

fun test(n: Int) {
    !(0 == 1)
}

After the quick-fix is applied:

fun test(n: Int) {
    0 != 1
}

Please note that this action may change code semantics if IEEE-754 NaN values are involved:

fun main() {
    println(!(Double.NaN >= 0)) // true
}

After the quick-fix is applied:

fun main() {
    println(Double.NaN < 0) // false
}
