RFR: 8268780: Use 'print_cr' instead of 'print' for the message 'eliminated <owner is scalar replaced>'

[Denghui Dong]

Hi,

Cound I have a review of this small fix that adds a line feed for the message 'eliminated <owner is scalar replaced>'.

When we run the following code and run `jstack <pid>`


    public static void main(String[] args) {
        for (int i = 0; i < 200000000; i++) {
            try {
                test();
            } catch (Exception e) {
            }
        }
    }

    private static void test() throws Exception {
        Object obj = new Object();
        synchronized (obj) {
            throw new Exception();
        }
    }


We could find that a frame that does not wrap properly.

        - eliminated <owner is scalar replaced> (a java.lang.Object)    at Test.main(Test.java:5)


Also, I noticed that this message has a correct line feed in the implementation of JavaVFrame.java.
