Yes, "Set ctx->opcode for decode_insn32()" applies and works for all
older stable releases.

So I'm not picking up this commit ("Make divd[u] handler method decodetree
compatible") for the stable releases (not even for 9.1), and do not pick
"Make divw[u] handler" either.

The rest from this pull request which are marked for-stable, are picked
up.
