On a real UltraSparc II CPU, the fmul8x16 instruction reads its first
input from any of the single-precision floating point registers.
But the emulator is reading the input as if the first operand encodes
a double-precision register, which in most cases will not contain the
right data and therefore the output of the emulated instruction is
just garbage.
