Before the endianness was specified on each call to read or write of the StreamReader / StreamWriter, but in practice it's extremely rare for streams to have data encoded in multiple different endiannesses, so we should optimize for the 99% use case. This makes the code cleaner and more general, but otherwise has NFC. llvm-svn: 296415
