Unsafe.getValue() on a flattenable but non flattened field

[Mandy Chung]

Yes, the user of `Unsafe` is responsible for asking whether a given
variable is flattened or not.

MemberName::isFlatValue is the API to determine if this member is
flattened.  Similarly, the modifier of java.lang.reflect.Field
carries a bit to indicate if flattened.  I'm considering adding
Unsafe::isFlattened(Field).
