movaps is a 128 bit aligned move, we need a 64 bit unaligned move, so use movsd. Fixes a crash in oleaut32_winetest tmarshal. Also add a comment about the use of movd instead of movq.

(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,
