Method elaborate

cranelift/codegen/src/egraph/mod.rs:1056–1068

Scoped elaboration: compute a final ordering of op computation for each block and update the given Func body. After this runs, the function body is back into the state where every Inst with an used result is placed in the layout (possibly duplicated, if our code-motion logic decides this is the best option). This works in concert with the domtree. We do a preorder traversal of the domtree, tracki

    /// for the rest of this block. (This subsumes GVN.)
