RFR - JDK-8210674 - Need to add examples for use of javac properties introduced by Raw String Literals

[Jim Laskey]

As per suggestions, I have reduced to


// key: compiler.err.unicode.backtick
// key: compiler.misc.feature.raw.string.literals
// key: compiler.warn.preview.feature.use.plural
// options: --enable-preview -source 12 -Xlint:preview

class RawStringLiteral {
    String m() {
        return `abc` + \u0060`def`;
    }
}

Which will reduce to two messages once out of preview.
