df_simulate_artificial_refs_at_top can be called to get a new value
of the sets at the top of the block (this is rarely used).
It would be trivial to define a similar set of functions that work
in the forwards direction. The only changes would be to process
the uses before the defs and properly rename the functions. This

It would be not be difficult to define a similar set of functions
that work in the forwards direction. In that case the functions
would ignore the use sets and look for the REG_DEAD and REG_UNUSED
notes.
