(see https://www.felixcloutier.com/x86/movd:movq). But there is another
movq with different encoding, which does not accept an integer register
as source (see https://www.felixcloutier.com/x86/movq). Older versions
of ML64 get confused and do not accept movq with integer registers,
but they translate movd to 64 bit, when 64 bit registers are used as
source, so we use that here. */
