[PATCH] D129001: [PGO] Report number of counts being dropped when a hash-mismatch happens.

[Rong Xu via llvm-commits]

It's almost impossible for the sum of a function's raw count values to
reach the max of uint64. If that happens, there must be something wrong.
We handle saturation in BFI weight where the type is int32.
