Early Reclamation Of Lazy Values In Scala

The goal of the project was to add to the Scala 3 compiler the ability to force nullify last uses of local variables, so that the GC will be able to collect it.

This issue can be illustrated by a simple snippet:

 def print_forever() =
   val ints = LazyList.from(0)
   ints.foreach(println)

This program crashes with an OOM, because the ints reference is still kept on the stack.
