Hello, regarding the Kotlin inspection `Useless call on not null type` which reports the likes of `String?.orEmpty` on not-null variables. Is there a way to extend this inspection to user functions? I have a helper `BigDecimal?.orZero() = this ?: BigDecimal.ZERO` and I'd like the IDE to report useless calls for it.

from a very quick glance at <https://github.com/JetBrains/intellij-community/blob/master/plugins/kotlin/idea/src/org/jetbrains/kotlin/idea/inspections/collections/UselessCallOnNotNullInspection.kt#L29|the source>, it doesn't look like so

<https://youtrack.jetbrains.com/issue/KTIJ-32458/Useless-call-on-not-null-type-Allow-extending-to-user-defined-functions>

Btw, you can “fork” most inspections in <https://github.com/dkandalov/live-plugin|LivePlugin> like this <https://gist.github.com/dkandalov/634dfc88ac92dcbc7f7e0df66ff8f9ba>  Although this one won’t report `BigDecimal.ONE.orZero()` out-of-the-box because `ONE` is a platform type. It will only work if you tweak the inspection code or do `BigDecimal.ONE!!.orZero()`.
