Summary

The current design of MachinePipeliner use DFA to do resource tracking in SMS,
but DFA only support InstrItins, and also has scaling limitation.

This patch extend SMS to allow Subtarget to use ProcResource in InstrSchedModel instead,
so that we can enable MachinePipeliner for PowerPC,
which will be posted for review in following patch.
