Title:
  qemu-arm does not reject vrintz on non-v8 cpu

Status in QEMU:
  New

Bug description:
  Hello,

  It seems that qemu-arm does not reject some v8-only instructions as it
  should, but executes them "correctly".

  For instance, while compiling/running some of the GCC ARM instrinsics tes=
ts, we noticed that
  vrintz should be rejected on cortex-a9 for instance, while it is executed=
 as if the instruction was supported.

  objdump says:
     1074c:       f3fa05a0        vrintz.f32      d16, d16
  and qemu -d in_asm says:
  0x0001074c:  f3fa05a0      vabal.u<illegal width 64>    q8, d26, d16

  The problem is still present in qemu-2.6.0
