Provide dbgs(), a circular-buffering debug output stream. By default it
...
simply passes output to errs(). If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it. This is handy when debugging very large inputs.

Add circular_raw_ostream, which buffers its output in a circular queue
...
and outputs it when explicitly flushed. The intent is to use it in
situations such as debug output logging where a signal handler can take
care of flushing the buffer at program termination.

Make some methods const. The only interesting change here is that
...
it changes raw_fd_ostream::preferred_buffer_size to return zero on
a scary stat failure instead of setting the stream to an error state.
This method really should not mutate the stream.

Makes '--comma-separated val1,val2' mean the same thing as

together as 'val1,val2'). Also declutters the main loop a bit.
