[Bug inline-asm/42321] New: NEON/VFP registers from inline assembly clobber list are saved/restored incorrectly

[siarhei dot siamashka at gmail dot com]

Test program:
/************************/
void f()
{
    asm volatile("veor d8, d8, d8" : : :"d8","d9","d10","d11","d14","d15");
}
/************************/

$ gcc -c -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O2 test.c
$ objdump -d test.o

00000000 <f>:
   0:   ed2d8b08        vpush   {d8-d11}
   4:   ed2deb04        vpush   {d14-d15}
   8:   f3088118        veor    d8, d8, d8
   c:   ecbd8b08        vpop    {d8-d11}
  10:   ecbdeb04        vpop    {d14-d15}
  14:   e12fff1e        bx      lr

The order of the last two vpop instructions is messed up.
