We can use SSE's 16 bit mul-hi to get a very good approximation to the ideal multiplier. This lets us trim several instructions. This removes the need for the constant 0x0001 and instead uses 0x8081. I've reordered the constants so that 0x8000 comes first, which helps trim an instruction here and there on ARM.
