Patch by Nitesh Jain.
Summary: On some target like MIPS32 we need to explicitly link atomic library for 64 bit atomic operations. This module then can be used in LLDB (http://reviews.llvm.org/D20464) or Libcxx (http://reviews.llvm.org/D16613) for explicitly link to atomic library.

LLVMConfig.cmake needs to set LLVM_BINARY_DIR differently based on whether or not it is the build directory or the install directory. The build directory just needs to set the value from the configuration, the install directory needs to set it to the install prefix.

This is the more-correct fix to out-of-tree building. AddLLVM.cmake relies on this variable being set, so we should make sure it is set in LLVMConfig.cmake.

This patch adds a new option LLVM_TOOLS_INSTALL_DIR which allows customizing the location executables and symlinks get installed to. This adds the functionality provided by autoconf's --bindir flag.

This allows customizing the location executables and symlinks get installed to,

With CMP0056, try_compile() uses also CMAKE_EXE_LINKER_FLAG.
It caused mismatch between CMAKE_CXX_FLAGS and CMAKE_EXE_LINKER_FLAGS, to fail to examine CXX_SUPPORTS_CXX11 with -m32.
FYI, before this, try_compile() tries without -m32 regardless of LLVM_BUILD_32_BITS.

Apparently cmake differentiates between Clang and AppleClang, and we
fail to color our diagnostics if you have the latter. Fix that.

The problem with plugins on Windows is that when building a plugin DLL it needs
to explicitly link against something (an exe or DLL) if it uses symbols from
that thing, and that thing must explicitly export those symbols. Also there's a
limit of 65535 symbols that can be exported. This means that currently plugins
only work on Windows when using BUILD_SHARED_LIBS, and that doesn't work with
MSVC.
This patch adds an LLVM_EXPORT_SYMBOLS_FOR_PLUGINS option, which when enabled
automatically exports from all LLVM tools the symbols that a plugin could want
to use so that a plugin can link against a tool directly. Plugins can specify
what tool they link against by using PLUGIN_TOOL argument to llvm_add_library.
The option can also be enabled on Linux, though there all it should do is
restrict the set of symbols that are exported as by default all symbols are
exported.
This option is currently OFF by default, as while I've verified that it works
with MSVC, linux gcc, and cygwin gcc, I haven't tried mingw gcc and I have no
idea what will happen on OSX. Also unfortunately we can't turn on
LLVM_ENABLE_PLUGINS when the option is ON as bugpoint-passes needs to be
loaded by both bugpoint.exe and opt.exe which is incompatible with this
approach. Also currently clang plugins don't work with this approach, which
will be fixed in future patches.

the C standard library implementation in use.
This works around a glibc bug in the backtrace() function where it fails to
produce a backtrace on x86_64 if libgcc / libunwind is statically linked.

- glibc is dynamically linked, and
- libgcc_s is unavailable (for instance, another library is being used to
provide the compiler runtime or libgcc is statically linked), and
- the target is x86_64.
If we run backtrace() and it fails to find any stack frames, try using
_Unwind_Backtrace instead if available.

Compiler-RT needs LLVM_LIBRARY_DIR, LLVM_BINARY_DIR.
Setting these in LLVMConfig.cmake will allow Compiler-RT to not need to run llvm-config as long as the LLVMConfig.cmake module is in the CMake module path.

Currently our cmake generates targets like check-llvm-unit and
check-llvm-transforms-loopunroll-x86, but not check-llvm-transforms or
check-llvm-transforms-adce. This is because the search for test suites
only lists the ones with a custom lit.cfg or lit.local.cfg.
Instead, we can do something a little smarter - any directory under
test that isn't called Inputs or inside a directory called Inputs is a
test suite.

Summary:
As per the discussion on LLVM-dev this patch proposes removing LLVM_ENABLE_TIMESTAMPS.
The only complicated bit of this patch is the Windows support. On windows we used to log an error if /INCREMENTAL was passed to the linker when timestamps were disabled.
With this change since timestamps in code are always disabled we will always compile on windows with /Brepro unless /INCREMENTAL is specified, and we will log a warning when /INCREMENTAL is specified to notify the user that the build will be non-deterministic.

Summary:
Historically, we had a switch in the Makefiles for turning on "expensive
checks". This has never been ported to the cmake build, but the
(dead-ish) code is still around.
This will also make it easier to turn it on in buildbots.

Summary: For Incremental LTO, we need to make sure that an old
cache entry is not used when incrementally re-linking with a new
libLTO.
Adding a global LLVM_REVISION in llvm-config.h would for to
rebuild/relink the world for every "git pull"/"svn update".
So instead only libLTO is made dependent on the VCS and will
be rebuilt (and the dependent binaries relinked, i.e. as of
today: libLTO.dylib and llvm-lto).

At the moment almost every lit.site.cfg.in contains two lines comment:
## Autogenerated by LLVM/Clang configuration.
# Do not edit!
The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from
configure_lit_site_cfg with the note and some useful information.

1) We need to add this flag prior to adding any other, in case the user has
specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag
causes -Werror builds to fail, and thus all config checks fail, until we add
the corresponding -fmodules flag. The modules selfhost bot does this, for
instance.
2) Delete module maps that were putting .cpp files into modules.
3) Enable -fmodules-local-submodule-visibility, to get proper module
visibility rules applied across submodules of the same module. Disable
-fmodules for C builds, since that flag is not available there.

This makes it so that when running 'ninja test-suite' from the top-level LLVM ninja build it *always* re-runs the ninja command in the test-suite directory.
This mechanism is required because the top-level ninja file doesn't have a view into the subdirectory dependency tree, so it can't know what, if anything, needs to be rebuilt.

What we are really trying to do here is to figure out if we are using
the 2015 STL. Unfortunately, so far as I know the MSVC STL does not
define a version macro that we can check directly. Instead I wrote a
check to see if char16_t works.

Otherwise users get messages from CheckAtomic about missing libatomic
instead of a sensible message that says "use GCC 4.7 or newer".
I structured the change along the lines of HandleLLVMStdlib.cmake, so
that the standalone build of Clang still gets the compiler version
check.
