Subject: Reapply "OnDiskHashTable: Use EndianStream.h to write little endian
 ostreams"

Committed this by accident before it was done last time.

Original message:

    Rather than rolling our own functions to write little endian data
    to an ostream, we can use the support in llvm's EndianStream.h.

    No functional change.
