[Bug debug/43260] New: Java static class members lack DWARF location info

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

Consider:

class jvstatic
{
  public static int STATIC = 1;
  public static final int CONST_STATIC = 2;

  public static void main (String[] args)
  {
    int i;
    for (i = 0; i < STATIC + CONST_STATIC; ++i)
      System.out.println ("Hi!");
  }
}

The DWARF debug info for either jvstatic.STATIC or jvstatic.CONST_STATIC don't
seem to include any hint at where these live in memory:
