Note, on big-endian hosts the FPSIMD view Vn and the SVE view Zn[127:0]
of the FPSIMD/SVE common register bits has the opposite endianness for
This only matters if mixing the two views: just from this patch I don't
know whether this is an issue for QEMU or not.
The kernel and gdb were recently found to be broken in this regard for
userspace  but the KVM interface should be unaffected.
