used when computing the gradient of `tf.sparse.segment_sum`.
    *   Renaming of tensorflow::int64 to int_64_t in numerous places (the former
        is an alias for the latter) which could result in needing to regenerate
        selective op registration headers else execution would fail with
        unregistered kernels error.

*   Modular File System Migration:

pkg bytes, method (*Buffer) Grow(int)
pkg bytes, method (*Reader) WriteTo(io.Writer) (int64, error)
