[PATCH v7 49/92] target/arm: Pass separate addend to {U, S}DOT helpers

[Richard Henderson <richard.henderson@linaro.org>]

For SVE, we potentially have a 4th argument coming from the
movprfx instruction.  Currently we do not optimize movprfx,
so the problem is not visible.

v4: Fix double addition (zhiwei).
v7: Split out type changes.
