Support Comparable#compareTo for boxed primitive in redundant boxing/unboxing analysis, along with CHECKCAST to java.lang.Comparable. Note that we can do that for Float and Double, too, because Float#compareTo(Float) and Double#compareTo(Double) are delegated to Float#compare(float, float) and Double#compare(double, double), respectively. Fuse specialized comparison for integers with conditional jumps if possible (both for Comparable#compareTo and Intrinsics#areEqual). #KT-11959 Fixed
