LGTM with a nit.

The $1 is unpredictable. You need to use a filecheck variable like so:
  ; MIPS64: daddu   $[[T0:[0-9]+]], $4, $5
  ; MIPS64: jr      $ra
  ; MIPS64: andi    $2, $[[T0]], 255

Hi Daniel!

I added the registers for the MIPS64 case in the remaining test cases and I also introduced the ALL check prefix.

Please review.
