This revision is now accepted and ready to land.

Thanks for adding me as a reviewer.
I am new to LLVM community and SCCP module. I am not sure if it is suitable for me to accept it. Just remind me if anyone is not comfortable.
The overall patch looks good to me as the first version. Although there must be some problems remained, I think we can work on top of this patch after merging iteratively. For example, I am playing function specialization for ThinLTO locally. And from the comments @wenlei give, PGO with function specialization is also interesting and charming. So after merging, we could work on specialization together for different aspects, like ThinLTO, PGO, bug fixes and Cost Model refactoring. So I choose to accept it.
Please wait 2~3 days to commit this in case there are more comments.
