The new C++ stdlib warning added in r335081 gets
triggered when compiling an assembly file with -x assembler-with-cpp.
This commit ensures that the C++ stdlib is not included when compiling assembly.
In general, it's not really useful to include the C++ stdlib search path when
compiling assembly source.

Xcode 10 removes support for libstdc++, but the users just get a confusing
include not file warning when including an STL header (when building for iOS6
which uses libstdc++ by default for example).
This patch adds a new warning that lets the user know that the libstdc++ include
path was not found to ensure that the user is more aware of why the error occurs.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.

Summary:
General idea is to utilize generic (mostly Generic_GCC) code
and get rid of Solaris-specific handling as much as possible.
In particular:
- scanLibDirForGCCTripleSolaris was removed, relying on generic
CollectLibDirsAndTriples
- findBiarchMultilibs is now properly utilized to switch between
m32 and m64 include & lib paths on Solaris
- C system include handling copied from Linux (bar multilib hacks)
Fixes PR24606.

removed as a duplicate header search path
The commit r126167 started passing the First index into RemoveDuplicates, but
forgot to update 0 to First in the loop that looks for the duplicate. This
resulted in a bug where an -iquoted search path was incorrectly removed if you
passed in the same path into -iquote and more than one time into -isystem.

for types which are used as pointees in PointerUnions, PointerIntPairs,
and DenseMap pointer keys.
This is part of a series of patches to allow LLVM to check for complete
pointee types when computing its pointer traits. This is absolutely
necessary to get correct (or reproducible) results for things like how
many low bits are guaranteed to be zero.
I think this is the last patch for getting Clang clean here!!!

Summary:
[ Copied from https://llvm.org/bugs/show_bug.cgi?id=25597 ]
Clang support for DragonFly BSD is lagging a bit, resulting in poor
support for c++.
DragonFlyBSD is unique in that it has two base compilers. At the time
of the last Clang update for DragonFly, these compilers were GCC 4.4 and
GCC 4.7 (default).
With DragonFly Release 4.2, GCC 4.4 was replaced with GCC 5.0, partially
because the C++11 support of GCC 4.7 was incomplete. The DragonFly
project will Release version 4.4 soon.
This patch updates the Clang driver to use libstdc++ from GCC 5.2 The
support for falling back to the alternate compiler was removed for two
reasons:
1) The last release to use GCC 4.7 is DF 4.0 which has already reached EOL
2) GCC 4.7 libstdc++ is insufficient for many "ports"
Therefore, I think it is reasonable that the development version of
clang expects GCC 5.2 to be in place and not try to fall back to another
compiler.
The attached patch will do this. The Tools.cpp file was signficantly
modified to fix the linking which had been changed somewhere along the
line. The rest of the changes should be self-explanatory.

No more hardcoded paths: clang will use -sysroot as gcc root location if
provided. Otherwise, it will search for gcc on the path. If not found it
will use the driver installed location.

Add Tool and ToolChain support for clang to target the NaCl OS using the NaCl
SDK for x86-32, x86-64 and ARM.
Includes nacltools::Assemble and Link which are derived from gnutools. They
are similar to Linux but different enought that they warrant their own class.
Also includes a NaCl_TC in ToolChains derived from Generic_ELF with library
and include paths suitable for an SDK and independent of the system tools.

Now that SmallString is a first-class citizen, most SmallString::str()
calls are not required. This patch removes a whole bunch of them, yet
there are lots more.
There are two use cases where str() is really needed:
1) To use one of StringRef member functions which is not available in
SmallString.
2) To convert to std::string, as StringRef implicitly converts while
SmallString do not. We may wish to change this, but it may introduce
ambiguity.

CloudABI is a pure cross compilation target. This means that we should
not add /usr/include and /usr/local/include. Instead, headers are stored
in $sysroot/$triple/include.
The method of going back to the sysroot (by using "../../..") is also
used in this function for some of the other environments (e.g., MinGW).

The main subtlety here is that the Darwin tools still need to be given "-arch
arm64" rather than "-arch aarch64". Fortunately this already goes via a custom
function to handle weird edge-cases in other architectures, and it tested.
I removed a few arm64_be tests because that really isn't an interesting thing
to worry about. No-one using big-endian is also referring to the target as
arm64 (at least as far as toolchains go). Mostly they date from when arm64 was
a separate target and we *did* need a parallel name simply to test it at all.
Now aarch64_be is sufficient.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for

This follows the LLVM change to canonicalise the Windows target triple
spellings. Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment. This is a
mechanical change to convert the triple use to reflect that change.

Up until now we were expecting that when libc++ is installed alongside
clang the headers would be in lib/, which was true if the configure
build was used and false if the cmake build was.
We've now corrected the configure build to install in include/, and
with this change we'll be able to find the correct headers with both
build systems.
