[vector] Miscellaneous tests to complete coverage of X-VectorBits.java plus fix

[Paul Sandoz]

Looks good.

I stumbled on the two overloaded ADDLong methods:

   3     static long ADDLong($type$[] a, int idx) {
   4         $type$ res = 0;
   5         for (int i = idx; i < (idx + SPECIES.length()); i++) {
   6             res += a[i];
   7         }
   8 
   9         return (long)res;
  10     }
  11 
  12     static long ADDLong($type$[] a) {
  13         long res = 0;
  14         for (int i = 0; i < a.length; i += SPECIES.length()) {
  15             $type$ tmp = 0;
  16             for (int j = 0; j < SPECIES.length(); j++) {
  17                 tmp += a[i + j];
  18             }
  19             res += (long)tmp;
  20         }
  21 
  22         return res;
  23     }


What if you rename the first ADDLongVector, then reuse it in the latter?
