[PATCH] D93254: [NFC][SampleFDO] Preparation to support multiple sections with the same type in ExtBinary format.

> To reduce the profile loading time during postlink phase when ThinLTO is enabled, we are going to split profile into two parts. One part contains profiles with inline instance and another part contains flattened profiles without inline instance in them.

For the flattened profile, do you explicitly flatten part of raw profile, or it's just the portion of function profile that does not have any inlinee profile?

> that could reduce the profile loading time for the large synthetic profile we use.

Is that the partial profile that is a merged profile from a few workloads?
