8d4abb2446 misched: TargetSchedule interface for machine resources.
Expose the processor resources defined by the machine model to the
scheduler and other clients through the TargetSchedule interface.

Normalize each resource count with respect to other kinds of
resources. This allows scheduling heuristics to balance resources
against other kinds of resources and latency.

412cd2f813 misched: Use the TargetSchedModel interface wherever possible.
Allows the new machine model to be used for NumMicroOps and OutputLatency.

Allows the HazardRecognizer to be disabled along with itineraries.

e1b5328717 Revert r164061-r164067. Most of the new subtarget emitter.
I have to work out the Target/CodeGen header dependencies
before putting this back.
