The change is an enhancement to https://reviews.llvm.org/D95988 so it is better to mention D95988 <https://reviews.llvm.org/D95988> in the description/commit log.

Before this patch UseProfileIndirectCallEdges is true for non-CS sampleFDO, now UseProfiledCallGraph is false by default so it change the behavior of non-CS sampleFDO. I will test UseProfiledCallGraph==true for non-CS sampleFDO and if performance is ok, we can enable UseProfiledCallGraph by default. How does it sound?
