* [Bug java/19285] New: Interfaces not initialized by static field access

Consider the following test case:
public class Test implements RuntimeConstants
{
public static void main(String[] args)
{
System.out.println(foo[0]);
}
}
interface RuntimeConstants
{
static int foo[] = {1};
}
Older bytecode compilers would implement the access to "foo" like so:
3: getstatic <Field RuntimeConstants.foo int[]>
However, presumably for reasons of binary compatibility, bytecode produced by
some modern Java compilers (javac 1.5.0 with "-target" >= 1.3) does the following:
3: getstatic <Field Test.foo int[]>
When "foo" is actually in an interface, there is a problem for GCJ because we
have no way to ensure that the interface gets initialized when it is accessed.
Initialization of a class does not itself cause initialization of its
superinterfaces.

This is somewhat related to PR 18868, which has to do
with field lookup in this situation.
For the interpreter this seems simple to fix.
For indirect-dispatch, the init-class call needs to
somehow use the really-declaring class as found during linking.
