  -----------
  [llvm-profdata] Stabilize iteration order for InstrProfWriter

If two functions are inserted to the same bucket, their order in the
serialized profile is dependent on StringMap iteration order, which is
not guaranteed to be deterministic.
(https://llvm.org/docs/ProgrammersManual.html#llvm-adt-stringmap-h).
Use a sort like we do in writeText.
