This doesn't build on top of tree sources.  It is missing the
mulv<mode>3_highpart change I mentioned in the riscv-gcc review.  Also, I
prefer that the order of the changelog entries match the order of hunks in
the patch, it is easier to review that way.  Otherwise, the patch is OK and
I committed it with minor changes.  Since I changed it, I need to send the
patch I did actually commit.

No known code changes, just fixes an inconsistency that was noticed.

Committed.
