[PATCH] [X86] Silvermont new scheduler model

[Alexey Volkov]

Hi atrick,

This patch enables Silvermont scheduler using new machine model.
I based it on Sandy Bridge model.
This model is not final and work is still in progress.
However there are substantial improvements on integer tests mainly because of better RAL with new scheduler.

I removed old scheduler model using itineraries completely.
Are itineraries needed in the new model or in PostRA scheduler?

Best regards,
