new Conditional Expression
fun MetadataProvider.newConditionalExpression(condition: Expression, thenExpr: Expression?, elseExpr: Expression?, type: Type? = UnknownType.getUnknownType(), code: String? = null, rawNode: Any? = null): ConditionalExpression
Creates a new ConditionalExpression. The MetadataProvider receiver will be used to fill different meta-data using Node.applyMetadata. Calling this extension function outside of Kotlin requires an appropriate MetadataProvider, such as a LanguageFrontend as an additional prepended argument.
