JVM_IR: optimize out redundant delegated property receiver fields

Browse Source 
Now this:

    class C {
        val x = something
        val y by x::property
    }

is *exactly* the same as this:

    class C {
        val x = something
        val y get() = x.property
    }

(plus a `getY$delegate` method)
