That is not sufficient: depending on the sse level and the saving style,
we have various amount of data to store. See fp_xsa

That is not sufficient: depending on the sse level and the saving style,
we have various amount of data to store. See fp_xsave_size computed in
init_fpu, we have to save all
* i386/i386/fpu.c: extend current getter and setter to support the
extended state; move the struct casting here to reuse the locking
and allocation logic for the thread state.
* i386/i386/fpu.h: update prototypes to accept generic thread state
* i386/i386/pcb.c: forward raw thread state to gett
