  19  * Test load unpack instructions

  21  * Example
  22  *     r0 = memubh(r1+#0)
  23  * loads a half word from memory and zero-extends the 2 bytes to form a word
  24  *
  25  * For each addressing mode, there are 4 tests
  26  *     bzw2          unsigned     2 elements
  27  *     bsw2          signed       2 elements
  28  *     bzw4          unsigned     4 elements
  29  *     bsw4          signed       4 elements
  30  * There are 8 addressing modes, for a total of 32 instructions to test
