Converts packed signed doubleword integers to packed double precision floating point.
Converts packed signed 32-bit integers to packed double precision floating point.
Considering only the low half of the register, each lane in `x` is interpreted as a
signed doubleword integer that is then converted to a double precision float. This
signed 32-bit integer that is then converted to a double precision float. This
instruction differs from fcvt_from_sint in that it converts half the number of lanes
which are converted to occupy twice the number of bits. No rounding should be needed
for the resulting float.
