It is beneficial for performance to assign a `Split` op to the same device
as its predecessor. This is because the weight of cut edges is always
minimized when the `Split` is with its predecessor. This colocation
constraint will be used by the placer graph optimization to assign a device
to the op.

This pass should run in the export pipeline after tf-replicate-to-island so
each replica has its own distinct (predecessor, Split) pair.

                ScriptBlock constraintsBlock = new ScriptBlock(null, "constraints");
                for (String config : constraints.keySet()) {
                    for (Statement statement : constraints.get(config)) {
                        constraintsBlock.add(statement);
                    }

=== [5.0] Improved support for dependency and version constraints

Through the Gradle 4.x release stream, new `@Incubating` features were added to the dependency resolution engine.
These include sophisticated version constraints (`prefer`, `strictly`, `reject`), dependency constraints, and `platform` dependencies.
