----------------
None of the AND/ADD/SUB instructions ending in mr are eligible for macrofusion as far as I know. Those all involve a load and a store which is not supported by macrofusion.

We also lost all the ADD*_DB instructions from the macrofusion list. I believe they are in the existing list incorrectly. So removing them is correct, but as far as I can see that change was not mentioned in the description of this patch.

Can we split the macrofusion refactoring out of this patch so we can review it separately and hopefully get it committed sooner than the other review feedback.
