[lworld] RFR: 8244796: [lworld] Javac does not compile test/hotspot/jtreg/runtime/valhalla/valuetypes/UnsafeTest.java anymore

[Srikanth Adayapalam]

Summary: Implement temporary typing rules for value class literals, these being:

    o Given a value class V that implements an interface I
        - Class<V>, Class<? extends V>, Class<? super V> are all malformed for the time being.
        - V.class and v.getClass() are to be typed temporarily as Class<? extends Object & I>
