how about I call this is_load_store_2_06() and add a comment. Horrible
but minimizes chance of misuse.

Actually it's is_opcode_31_load_store_2_06() - which is even more
horrible :)

But you can probably fold it in to the main routine and then call that
is_load_store_2_06(). Or whatever seems best, but yeah I think we should
make it very clear that it's only for 2.06.
