[PATCH v2 0/6] target/arm: assorted mte fixes

[Richard Henderson]

The first patch is unchanged from

Supercedes: <20240131003557.176486-1-richard.henderson@linaro.org>

while the remaining patches replace

Supercedes: <20240205023948.25476-1-richard.henderson@linaro.org>

While digging through Gustavo's test case, wondering why it
should be failing at all, I finally noticed that we weren't
overflowing MTEDESC.SIZEM1, but underflowing (-1).  Oops.

But I did find a few other points by inspection where we
weren't properly handling or supplying MTEDESC.
