27b8e80941Smrg *
28b8e80941Smrg * Takes the leaves of expression trees and makes them dereferences of
29b8e80941Smrg * assignments of the leaves to temporaries, according to a predicate.
30b8e80941Smrg *
31b8e80941Smrg * This is used for automatic function inlining, where we want to take
32b8e80941Smrg * an expression containing a call and move the call out to its own
33b8e80941Smrg * assignment so that we can inline it at the appropriate place in the
34b8e80941Smrg * instruction stream.
