ProfileSampleAccurate is used to indicate the profile has exact match to the code to be optimized. Previously ProfileSampleAccurate is handled in ProfileSummaryInfo::isColdCallSite and ProfileSummaryInfo::isColdBlock. A better solution is to initialize function entry count to 0 when ProfileSampleAccurate is true, so we don't have to handle ProfileSampleAccurate in multiple places.
