| Designates that a field, return value, argument, or a variable is supposed
to be an
String.intern interned string.
In many places in the istack, we assume Strings to be interned for
the performance reason. Similarly, In many other places, we don't
make such an assumption for the performance reason (because intern
isn't free.)
Therefore, distinguishing which part is supposed to be interned and
which part is supposed to be not is important. This annotation
allows us to capture that in the code.
