// The `Kind` is a single byte identifying the type of data that is actually
// stored in a `ProfileBufferEntry`, as per the list in
// `FOR_EACH_PROFILE_BUFFER_ENTRY_KIND`.
//
// This byte is also used to identify entries in ProfileChunkedBuffer blocks,
// for both "legacy" entries that do contain a `ProfileBufferEntry`, and for
// new types of entries that may carry more data of different types.
// TODO: Eventually each type of "legacy" entry should be replaced with newer,
// more efficient kinds of entries (e.g., stack frames could be stored in one
// bigger entry, instead of multiple `ProfileBufferEntry`s); then we could
// discard `ProfileBufferEntry` and move this enum to a more appropriate spot.
