      Description

        Current C1 does not handle Class.isPrimitive intrinsic, while C2 does. Class.isPrimitive is important enough to consider intrinsifying even in C1: there are 150+ usages in JDK alone (java.lang.invoke and other reflective stuff are heavy users), and some expected usages in JDK-8150465.
