The patch tries to make sample profile loader independent of profile format change. It moves compact format related code into FunctionSamples and SampleProfileReader classes, and sample profile loader only has to interact with those two classes and will be unaware of profile format changes. The cleanup also contain some fixes to further remove the difference between compactbinary format and binary format. After the cleanup using different formats originated from the same profile will generate the same binaries, which we verified by compiling two large server benchmarks w/wo thinlto.
