ART: Implement SuperblockCloner.
SuperblockCloner provides a feature of cloning subgraphs in a
smart, high level way without fine grain manipulation with IR;
data flow and graph properties are resolved/adjusted automatically.
The clone transformation is defined by specifying a set of basic
blocks to copy and a set of rules how to treat edges, remap their
successors. By using this approach such optimizations as Branch
Target Expansion, Loop Peeling, Loop Unrolling can be implemented.
Test: superblock_cloner_test.cc.
