This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.

output file gets deleted if the tool is interrupted or encounters an
error.

 - Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

Make some more changes suggested by Chris.  Manipulators go away.

llvm-svn: 75472

Make changes suggested by Chris and eliminate newly-added raw_ostream
hooks as they're no longer needed.

The major change with this patch is to make formatted_raw_ostream usable
by any client of raw_ostream.
