      <p>This only expands 32-bit divisions to 64-bit, since the smaller
        sizes requires more work at the node level, but is certainly
        possible and will happily continue to experiment with seeing if
        it can be implemented.  This was fun to do!</p>
      <p>The test "bench/bdiv.pp" (also "tests/test/cg/tmoddiv6.pp"
        which just includes the given file) is my benchmark test for
        division and modulus operations if anyone wants to see if they
        can make the fundamental routine faster on any platform.</p>
