2701e04c3fSmrg *
2801e04c3fSmrg * Takes the leaves of expression trees and makes them dereferences of
2901e04c3fSmrg * assignments of the leaves to temporaries, according to a predicate.
3001e04c3fSmrg *
3101e04c3fSmrg * This is used for automatic function inlining, where we want to take
3201e04c3fSmrg * an expression containing a call and move the call out to its own
3301e04c3fSmrg * assignment so that we can inline it at the appropriate place in the
3401e04c3fSmrg * instruction stream.
