All the information in the MIPS c0_status register is priviledged.
Nothing that would constitute part of the thread context.
The one flag one could possibly argument about might be c0_status.fr
but none of the ABIs or tools or application software can make use
of it.
So for consistency with restore_sigcontext32(), which does not
restore c0_status register, this patch remove the saving part.

The struct mips_fpu_soft_struct and mips_fpu_hard_struct are
completely same now and the kernel fpu emulator assumes that. This
patch unifies them to mips_fpu_struct and get rid of mips_fpu_union.

Rename the 64-bit sc_hi and sc_lo arrays to use the same names
as the 32-bit struct sigcontext (sc_mdhi, sc_hi1, et cetera).

Cannot build MIPS now.
We need to change offset.c to asm-offsets.c
