Rong Xu d7ef0c3970 [llvm-profdata] Improve profile supplementation
Current implementation promotes a non-cold function in the SampleFDO profile
into a hot function in the FDO profile. This is too aggressive. This patch
promotes a hot functions in the SampleFDO profile into a hot function, and a
warm function in SampleFDO into a warm function in FDO.

Nathan Slingerland 48dd080c77 [PGO] Handle and report overflow during profile merge for all types of data
