  28  * Takes the leaves of expression trees and makes them dereferences of
  29  * assignments of the leaves to temporaries, according to a predicate.
  30  *
  31  * This is used for automatic function inlining, where we want to take
  32  * an expression containing a call and move the call out to its own
  33  * assignment so that we can inline it at the appropriate place in the
  34  * instruction stream.
