Android profile runs don't always fully write out the profile data. In this case, the corrupted profile data is successfully uploaded, but future profile-use PGO builds try to merge the data and fail. Retrying the profile-use builds doesn't help, since they all pull from the same job that published the corrupt data. We can detect this in the run task by using llvm-profdata merge, and if the merge fails the task can automatically be retried. Note that the data gets redundantly merged in the profile-use build, but it may not be possible to run the merge in the run task on all platforms (eg: OSX), so we have to keep the merge there as well.
