hujun5 908df725ad arch: use up_current_regs/up_set_current_regs replace CURRENT_REGS 
reason:
1 On different architectures, we can utilize more optimized strategies
  to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

code size
before
    text    data     bss     dec     hex filename

 262844   49985   63893  376722   5bf92 nuttx

size change -4

Configuring NuttX and compile:
$ ./tools/configure.sh -l qemu-armv8a:nsh_smp
$ make
Running with qemu
$ qemu-system-aarch64 -cpu cortex-a53 -smp 4 -nographic \
   -machine virt,virtualization=on,gic-version=3 \
   -net none -chardev stdio,id=con,mux=on -serial chardev:con \
   -mon chardev=con,mode=readline -kernel ./nuttx
