Summary: The PGO counter reading will add cold and inlinehint (hot) attributes to functions that are very cold or hot. This was using hardcoded thresholds, instead of the profile summary cutoffs which are used in other hot/cold detection and are more dynamic and adaptable. Switch to using the summary-based cold/hot detection. The hardcoded limits were causing some code that had a medium level of hotness (per the summary) to be incorrectly marked with a cold attribute, blocking inlining.
