JDK-8215210: [macos] Hangul text does not shape to the precomposed form on JDK8u

[Hohensee, Paul]

There's been no response on 2d-dev, so I'm ok with going ahead with this.

    This looks reasonable to me based on prr's description, but I've got almost no experience in this area. I'd cross-post to 2d-dev to see what they think. They might be interested in your regression tests.

        Hi all,
        
        could you please review this downport of
        https://bugs.openjdk.java.net/browse/JDK-8215210 to openjdk 8u?
        
        Link to webrev: http://cr.openjdk.java.net/~yan/8215210/webrev.0/
        
        There is a single digit change discovered by prr and a couple of
        regression tests:
        
        one verifies that required shaping works as expected and another -- that
        there's no obvious regression for JDK-8201801

        Thank you!
