Subject: When scheduling a block in parts, keep track of the overall
 instruction index across each part. Instruction indices are used to make live
 range queries, and live ranges can extend beyond scheduling region
 boundaries.

Refactor the ScheduleDAGSDNodes class some more so that it
doesn't have to worry about this additional information.
