[Qing Shan Zhang via Phabricator via llvm-commits]

I am sorry that, I didn't put enough background for this change. The idea is not for per-function basis.  We have the pre-ra scheduler and post-ra scheduler you know, and they should be able to be configured for different CPU processor. (Some cpu might need the post-ra scheduler, and some didn't, though we always enable it for all cpus) This is done by adding features and included by different cpu.  And it also gives us the ability to turn on/off the specific scheduler.
