Detect shadowing of to (and other infix) operators

[kiiadi]

Example code that accidentally calls the wrong method

interface Person {
    val displayName: String
}

object Hello {
    fun to(p: Person) {
        println("Hello ${p.displayName}!!")
    }
}

object Student {
    val displayName = "Student"
}

fun main(args: Array<String>) {
    //Should print "Hello Student!!"    
    Hello.to(Student)
}

This actually calls kotlin.to in the standard library.
