raw_stream formatter: [Win32] Use std::signbit() if available, instead of _fpclass().

FIXME: It should be generic to C++11. For now, it is dedicated to mingw-w64.

Add a wrapper for open.

This centralizes the handling of O_BINARY and opens the way for hiding more
differences (like how open behaves with directories).

Create files with mode 666. This matches the behavior of other unix tools.

Remove the program class.

It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

Don't try to generate crash diagnostics if we had an I/O failure. It's very
likely the crash diagnostics generation will fail as well.

Don't crash if write_impl() leaves less buffer space available than expected.

This was tickled by a Clang diagnostic; Clang test case to follow.

Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

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. =]

Reapply 'Add reverseColor to raw_ostream'.

Patch by Seth Cantrell, with a minor fix for mingw by me.

Fix integer overflow bug in raw_ostream::write. This showed up as a

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

size and copying the remainder into the buffer.

Thanks to Dan for pointing this out.

This caps the number of write(2) calls per string to a maximum of 2.
