    [AArch64] When unavailable, fetch VG from ptrace.
   
    I was doing some SVE tests on system QEMU and noticed quite a few failures
    related to inferior function calls. Any attempt to do an inferior function
    call would result in the following:
   
    Unable to set VG register.: Success.
   
    This happens because, after an inferior function call, GDB attempts to restore
    the regcache state and updates the SVE register in order. Since the Z registers
    show up before the VG register, VG is still INVALID by the time the first Z
    register is being updated. So when executing the following code in
    aarch64_sve_set_vq:
   
    if (reg_buf->get_register_status (AARCH64_SVE_VG_REGNUM) != REG_VALID)
      return false;
   
    By returning false, we signal something is wrong, then we get to this:
   
      /* First store vector length to the thread.  This is done first to ensure the
         ptrace buffers read from the kernel are the correct size.  */
      if (!aarch64_sve_set_vq (tid, regcache))
        perror_with_name (_("Unable to set VG register."));
   
    Ideally we'd always have a valid VG before attempting to set the Z registers,
    but in this case the ordering of registers doesn't make that possible.
   
    I considered reordering the registers to put VG before the Z registers, like
    the DWARF numbering, but that would break backwards compatibility with
    existing implementations. Also, the Z register numbering is pinned to the V
    registers, and adding VG before Z would create a gap for non-SVE targets,
    since we wouldn't be able to undefine VG for non-SVE targets.
   
    As a compromise, it seems we can safely fetch the VG register value from
    ptrace. The value in the kernel is likely the updated value anyway.
   
    This patch fixed all the failures i saw in the testsuite and caused no further
    regressions.
