It's a bug specific to the old H8/300 support (ie, works correctly on H8/300H
and H8/300s variants). The 24bit shift is implemented as a byte copy from the
high byte to the low bite, then extending the sign bit through the two middle
bytes and into the high byte. But the extending part had two typos which
prevented extending into the upper middle and upper bytes.
