While std::error_code itself seems to work OK in all platforms, there
are few annoying differences with regards to the std::errc enumeration.
This patch adds a simple llvm enumeration, which will hopefully avoid build
breakages in other platforms and surprises as we get more uses of
std::error_code.

This is a minimal change to remove the header. I will remove the occurrences
of "using std::error_code" in a followup patch.

The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.
The cases where the general idea needed some tweaking:
* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.
* Template specialization had to be moved to the std namespace in this
patch set already.
* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.
Despite these shortcomings I think this is still a good thing. Some reasons:
* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

MSVC doesn't seem to provide any is_error_code_enum enumeration for the
windows errors.
Fortunately very few places in llvm have to handle raw windows errors, so
we can just construct the corresponding error_code directly.

There is no std::error_code::success, so this removes much of the noise
in transitioning to std::error_code.

Before this patch the unix code for creating hardlinks was unused. The code
for creating symbolic links was implemented in lib/Support/LockFileManager.cpp
and the code for creating hard links in lib/Support/*/Path.inc.
The only use we have for these is in LockFileManager.cpp and it can use both
soft and hard links. Just have a create_link function that creates one or the
other depending on the platform.

This reverts commits r203136, r203137, and r203138.
This code doesn't build on Windows. Even on Vista+, Windows requires
elevated privileges to create a symlink. Therefore we can't use
symlinks in the compiler. We'll have to find another approach.

This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Before this patch they would take an boolean argument to say if the path
already existed. This was redundant with the returned error_code which is able
to represent that. This allowed for callers to incorrectly check only the
existed flag instead of first checking the error code.
Instead, pass in a boolean flag to say if the previous (non-)existence should be
an error or not.
Callers of the of the old simple versions are not affected. They still ignore
the previous (non-)existence as they did before.

I found that swapping the order of some header files helped fix a
build issue that we're seeing on mingw32. Without the swap, windows.h
was being included before _WIN32_WINNT was being defined and the
CreateHardLinkW function was #ifdef'd out.
It looks like the header is mainly used to get the SHGetFolderPathW
function, so I don't think that there'll be much fallout from the
switch.
Suggested by Alex Crichton. Thanks!
