I've had a review comment in private email that this patch
slows down ffmpeg by a little over 4% (in a linux-user execution
run where about 5% of instructions were an affected vld/vst). So
perhaps the right approach is to increase the max-ops-per-insn limit
and update the guidance in tcg/README instead?
