[Bug java/19870] gcj -C doesn't generate accessors for private members in inner class

["mckinlay at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

gcj is generating code which references private members across class boundaries,
which isn't legal at the class/VM level. To fix this, we need to generate
package-private accessor methods when a private member is referenced from an
enclosed or enclosing class.

eg: jikes generates:

Method name:"main" public static Signature: (java.lang.String[])void
Attribute "Code", length:38, max_stack:2, max_locals:1, code_length:10
  0: getstatic <Field java.lang.System.out java.io.PrintStream>
  3: invokestatic <Method A$B.access$0 ()int>
  6: invokevirtual <Method java.io.PrintStream.println (int)void>
  9: return
Attribute "LineNumberTable", length:10, count: 2
  line: 10 at pc: 0
  line: 11 at pc: 9

Method name:"access$0" static Signature: ()int
Attribute "Synthetic", length:0
Attribute "Code", length:28, max_stack:1, max_locals:0, code_length:4
  0: getstatic <Field A$B.i int>
  3: ireturn
Attribute "LineNumberTable", length:6, count: 1
  line: 3 at pc: 0
