Incorrect bytecode generated for static methods on interfaces

Calls to static interface methods compile on Java 8 but not on Java 9 because of a new bytecode restriction. As the usage of static interface methods increases, this problem will manifest more. I ran into it while using the AWS SDK (2.0 preview) which makes extensive usage of these methods.

The original ticket had a repro here: https://github.com/ztellman/java9-failure

Cause: The JVM spec mandates that invocations to static interface methods refer to an InterfaceMethodref entry in the constant pool rather than simply to a Methodref. See https://docs.oracle.com/javase/specs/jvms/se9/html/jvms-5.html#jvms-5.4.3.3, describing the resolution rules for Methodrefs:

Bytecode verification was tightened in Java 9 to check for this: https://bugs.openjdk.java.net/browse/JDK-8145148

ASM 5.1+ provide support for this.

Approach: First, upgrade to min Java 8 and latest ASM (6.2 right now) - this is now covered in ticket CLJ-2363. The patch here assumes CLJ-2363 has been completed as a baseline. The change here calls the newer ASM method to gen a static method call with awareness of static interface methods.
