JDK 9 RFR of fallthrough fix in ASM

[Joe Darcy]

Hello,

Please review this change to suppress a fall-through warning recently 
sync'ed into ASM:

+    @SuppressWarnings("fallthrough")
     void set(final int type, final String strVal1, final String strVal2,
             final String strVal3) {
         this.type = type;


The switch statement is

        switch (type) {
        case ClassWriter.CLASS:
            this.intVal = 0;     // intVal of a class must be zero, see 
visitInnerClass
        case ClassWriter.UTF8:
        case ClassWriter.STR:
        case ClassWriter.MTYPE:
        case ClassWriter.TYPE_NORMAL:
            hashCode = 0x7FFFFFFF & (type + strVal1.hashCode());
            return;
        case ClassWriter.NAME_TYPE: {
            hashCode = 0x7FFFFFFF & (type + strVal1.hashCode()
                    * strVal2.hashCode());
            return;
        }
        // ClassWriter.FIELD:
        // ClassWriter.METH:
        // ClassWritehr.IMETH:
        // ClassWriter.HANDLE_BASE + 1..9
        default:
            hashCode = 0x7FFFFFFF & (type + strVal1.hashCode()
                    * strVal2.hashCode() * strVal3.hashCode());
        }
    }

Thanks,
