Remove .hot and .unlikely prefixes from function section names.
This code currently relies on static methods in ProfileSummary to determine whether a function is hot or unlikley. I am refactoring the ProfileSummary code and these methods will be removed. As discussed offline, the right way to re-introduce this is to add a pass to annotate functions with unlikely/hot hints and use the hints to determine the prefix here.
