Daniel Sanders 6d286aba49 [gicombiner] Add GIMatchTree and use it for the code generation ... Summary: GIMatchTree's job is to build a decision tree by zipping all the GIMatchDag's together. Each DAG is added to the tree builder as a leaf and partitioners are used to subdivide each node until there are no more partitioners to apply. At this point, the code generator is responsible for testing any untested predicates and following any unvisited traversals (there shouldn't be any of the latter as the getVRegDef partitioner handles them all). Note that the leaves don't always fit into partitions cleanly and the partitions may overlap as a result. This is resolved by cloning the leaf into every partition it belongs to. One example of this is a rule that can match one of N opcodes. The leaf for this rule would end up in N partitions when processed by the opcode partitioner. A similar example is the getVRegDef partitioner where having rules (add $a, $b), and (add ($a, $b), $c) will result in the former being in the partition for successfully following the vreg-def and failing to do so as it doesn't care which happens.
