ae692f2bae misched: Infrastructure for weak DAG edges. 
This adds support for weak DAG edges to the general scheduling
infrastructure in preparation for MachineScheduler support for
heuristics based on weak edges.

953be893e8 misched preparation: rename core scheduler methods for consistency. 
We had half the API with one convention, half with another. Now was a
good time to clean it up.

4c72720427 misched preparation: modularize schedule verification. 
ScheduleDAG will not refer to the scheduled instruction sequence.

ee498d3254 VLIW specific scheduler framework that utilizes deterministic finite automaton (DFA). 
This new scheduler plugs into the existing selection DAG scheduling framework. It is a top-down critical path scheduler that tracks register pressure and uses a DFA for pipeline modeling.

Patch by Sergei Larin!
