f6b47d2a4f [Power9] Add a specific heuristic to schedule the addi before the load 
When we are scheduling the load and addi, if all other heuristic didn't take effect,
 we will try to schedule the addi before the load, to hide the latency, and avoid the
 true dependency added by RA. And this only take effects for Power9.

d1b34e99f6 [NFC][PowerPC] Custom PowerPC specific machine-scheduler 
This patch lays the groundwork for extending the generic machine scheduler by providing a PPC-specific implementation.
There are no functional changes as this is an incremental patch that simply provides the necessary overrides which just
encapsulate the behavior of the generic scheduler. Subsequent patches will add specific behavior.
