[PATCH v3 0/9] target/arm: Implement SVE2 Crypto Extensions

[Richard Henderson]

Stephen, what I was looking for when I talked about modifying
the existing helpers is patch 1, which simplifies the final 3
patches for the new SVE2 insns.

In the process I found that the existing implementation of the
AdvSIMD insns is buggy wrt SVE.  We need to clear the bits in
the Zreg destination beyond the first 128.

I could have done this via clear_vec_high in translate-a64.c,
but since we already have a function call, we're better off
doing the clearing out of line.  This means adding a desc
parameter so that we know the total vector length.
