Implement late lambda lift
Summary:
This implements a selective lambda-lifting pass late in the STG
pipeline.
Lambda lifting has the effect of avoiding closure allocation at the cost
of having to make former free vars available at call sites, possibly
enlarging closures surrounding call sites in turn.
We identify beneficial cases by means of an analysis that estimates
closure growth.
