pc kernel: simulate FXSAVE/FXRSTOR tag-byte from x87 tag-word, copy fp state across fork
the tag-word is not compatible between x87 and sse, have to convert
properly for emulation to work.
we now copy fp state across fork (again!) to preserve FCW and MXCSR
registers. this might not be neccesary as we could probably just
get the current value for the curren process and avoid the fpsave()
call, but become conservative again.
