In SSA, how do you express the notion that a variable is no longer
live after a particular program point?  If I have two variables live
upon entry to a block, but the last use of one precedes the last use of
the other, how is that information expressed, or is your argument that it is
more easily computed in an SSA framework than the current IL?
