Use the new script to sort the includes of every file under lib.
...
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

raw_ostream: while it is generally desirable to do larger writes, it can lead to
...
inefficient file system buffering if the writes are not a multiple of the desired
buffer size. Avoid this by limiting the large write to a multiple of the buffer

Fix the rest of rdar://8318441 which happens when a raw_fd_ostream

(e.g. errs()) fails in close() due to (e.g.) a broken pipe. As

the raw_ostream dtor would report a fatal error. There is nothing
the client can do about this and we have no way to report the error,
so just eat it.
