RFR: 8325257: jshell reports NoSuchFieldError with instanceof primitive type

[Aggelos Biboudis]

Fixed compiler bug during lowering of the type test, where the let expression was using the `expr` of the old `tree` and not of the translated one. The latter manifested as a JShell error. Added compiler test as well. e.g., 


class $JShell$2 {
    
    $JShell$2() {
        super();
    }
    public static boolean $1;
    
    public static Object do_it$() throws Throwable {
        return Boolean.valueOf($1 = (let /*synthetic*/ final Object tmp184$ = $JShell$1.o 
                                     in tmp184$ != null && o instanceof Long));                          
                                                        // ^
    }
}
