Trying to solve this problem by avoiding copy-propagation in special cases
is definitely not the right approach.

Any time we do a copy propagation or redundancy elimination we run the risk
of possibly creating overlapping lifetimes for objects which did not previously
overlap.

Our focus needs to be on figuring out why we did not coalesce everything to
a single variable.
