(
Multiplying two 16-bit numbers yields a 32-bit number.
MUL2 returns the lowest 16 bits, we want the highest.
We split each short into hi and lo bytes, then sum
the following multiplications:
31..24 23..16 15..08 07..00
{ ahi * bhi }
{ alo * bhi }
{ ahi * blo }
{ alo * blo }
Bits 07..00 can be ignored, but each sum in bits 23..16
can end up overflowing into bit 24.
