Summary:
This new toolchain uses primarily LLVM-based tools, eg. compiler-rt, lld,
libcxx, etc. Because of this, it doesn't require neither an existing GCC
installation nor a GNU environment. Ideally, in a follow-up patch we
would like to add a new --{llvm|clang}-toolchain option (similar to
--gcc-toolchain) in order to allow the use of this toolchain with
independent Clang builds. For the time being, we use the --sysroot
option just to test the correctness of the paths generated by the
driver.

If clang was configured with a custom gcc toolchain (either by using GCC_INSTALL_PREFIX in cmake or the equivalent configure command), the path to the custom gcc toolchain path takes precedence to the one specified by -ccc-install-dir. This causes several regression tests to fail as they will be using an unexpected path. Adding the switch --gcc-toolchain="" in each test command is not enough as the hexagon toolchain implementation in the driver is not evaluating this argument. This commit modifies the hexagon toolchain to take the --gcc-toolchain="" argument into account when deciding the toolchain path, similarly to what is already done for other targets toolchains. Additionally, the faulty regression tests are modified in order to --gcc-toolchain="" be passed to the commands.

This is a very basic toolchain. It supports cross-compiling Windows (primarily
inspired by the WoA target). It is meant to use clang with the LLVM IAS and a
binutils ld-compatible interface for the linker (eventually to be lld). It does
not perform any "standard" GCC lookup, nor does it perform any special
adjustments given that it is expected to be used in an environment where the
user is using MSVCRT (and as such Visual Studio headers) and the Windows SDK.
The primary runtime library is expected to be compiler-rt and the C++
implementation to be libc++.
It also expects that a sysroot has been setup given the usual Unix semantics
(standard C headers in /usr/include, all the import libraries available in
/usr/lib). It also expects that an entry point stub is present in /usr/lib
(crtbegin.obj for executables, crtbeginS.obj for shared libraries).
The entry point stub is responsible for running any GNU constructors.

Specifically, this patch:
* Adds support for searching environment variables for VS 12.0
* Correctly locates include folders for Windows SDK 8.x (this was
previously broken, and would cause clang to error)
* Prefers locating link.exe in the same location as cl.exe. This
is helpful in case another link.exe is in the path earlier than

* Minor cleanup in the registry reading code to make it more

modern Debian-based distributions) due to on-going multiarch madness.
It appears that when the multiarch heeader search support went into the
clang driver, it went in in a quite bad state. The order of includes
completely failed to match the order exhibited by GCC, and in a specific
case -- when the GCC triple and the multiarch triple don't match as with
i686-linux-gnu and i386-linux-gnu -- we would absolutely fail to find
the libstdc++ target-specific header files.
I assume that folks who have been using Clang on Ubuntu 32-bit systems
have been applying weird patches to hack around this. I can't imagine
how else it could have worked. This was originally reported by a 64-bit
operating system user who had a 32-bit crosscompiler installed. We tried
to use that rather than the bi-arch support of the 64-bit compiler, but
failed due to the triple differences.
I've corrected all the wrong orderings in the existing tests and added
a specific test for the multiarch triple strings that are different in
a significant way. This should significantly improve the usability of
Clang when checked out vanilla from upstream onto Ubuntu machines with
an i686 GCC installation for whatever reason.

r197490 changed the behavior of LIBRARY_PATH to try to match GCC's behavior
for cross compilers and make clang work better on "bare metal" targets.
Unfortunately that change is breaking a number of MacPorts projects because
the LIBRARY_PATH environment variable is being ignored when compiling on a
64-bit host for a 32-bit target. Because the host and target architectures
differ, isCrossCompiling returns true. This does not make sense for Darwin,
where multiple architectures are supported natively via "fat" Mach-O slices
and where development is generally done against SDKs regardless. This patch
fixes the problem by overriding isCrossCompiling to return false for Darwin
toolchains.

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.
