Konstantin Belousov 57f6622f92 For i386, remove config options CPU_DISABLE_CMPXCHG, CPU_DISABLE_SSE
and device npx.

This means that FPU is always initialized and handled when available,
and SSE+ register file and exception are handled when available.  This
makes the kernel FPU code much easier to maintain by the cost of
slight bloat for CPUs older than 25 years.

CPU_DISABLE_CMPXCHG outlived its usefulness, see the removed comment
explaining the original purpose.
