[Bug middle-end/16187] New: extra casts to unsigned int generated for array references

["dann at godzilla dot ics dot uci dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

The .vars dump for this function:

int f1(int *  data, int j)
{
      return  data[j];                                 
}

looks like: 

  return *((int *)((unsigned int)j * 4) + data);

The cast to "unsigned int" is probably not needed, emitting it increases the
number of statements generated, so it probably increases the memory consumption
and the amount of work the optimizers have to perform.
