Title:
  illegal instructions for AArch64 ARMv8

Status in QEMU:
  New

Bug description:
  The test case is in the attachment. To reproduce as following (I tried both 
GCC and Clang):
  $aarch64-linux-gnu-gcc qemu.c -o test
  $./test
  qemu: uncaught target signal 4 (Illegal instruction) - core dumped
  Illegal instruction (core dumped)

  In the test case, 3 intrinsics are tested: vqmovunh_s16,  vqmovuns_s32, 
vqmovund_s64. They will be compiled into instructions:
  SQXTUN Bd, Hn
  SQXTUN Hd, Sn
  SQXTUN Sd, Dn.

  QEMU is get from trunk git://git.qemu.org/qemu.git. Other instructions
  work well. It seems that these instructions are not supported in QEMU.
  Is this a bug?
