Save and restore the high FP registers in {g|s}_mcontext(). Note that we currently do not keep track of whether the thread has actually used the high FP registers before. If not, we should not save them in the context which automaticly means that we also would not restore them from the context. For now, do it unconditionally so that we can reach functional completeness.
