Peter Maydell d43ebd9dc8 target/arm: Implement MVE VADDLV 
Implement the MVE VADDLV insn; this is similar to VADDV, except
that it accumulates 32-bit elements into a 64-bit accumulator
stored in a pair of general-purpose registers.

# The _rev suffix indicates that Vn and Vm are reversed. This is
# the case for shifts. In the Arm ARM these insns are documented
# with the Vm and Vn fields in their usual places, but in the
# assembly the operands are listed "backwards", ie in the order
# Qd, Qm, Qn where other insns use Qd, Qn, Qm. For QEMU we choose
# to consider Vm and Vn as being in different fields in the insn.
# This gives us consistency with A64 and Neon.
