CMake won't expand the dependency graph for us if the dependencies are in
another project, which leads to link errors in the standalone build.
This is a refinement of r200765.

r200744 moved this into cmake/config-ix.cmake, so that it would happen very
early in the build process. However, standalone builds of Clang and other
external projects never include this file (which is correct).
Now, -stdlib=libc++ and the LLVM_COMPILER_IS_GCC_COMPATIBLE option are
both set in a new include file, HandleLLVMStdlib, which is included by
both config-ix.cmake and HandleLLVMOptions.cmake. This preserves existing
behavior for projects relying on HandleLLVMOptions and still does the
right thing for builds of LLVM itself.

CMake's target_link_libraries() will manage dependencies.
Configuration time may be reduced by a few seconds.

In trunk, every users assume add_llvm_loadable_module as "loadable module" and no one sets neither SHARED, ... nor also MODULE!
Unfortunately, all loadable modules were linked as not "MODULE" but "SHARED".
If this change caused any regressions, I wish guys to fix it properly. ;)

If LLVM_ENABLE_LIBCXX is specified, we should append -stdlib=libc++ to build
flags as early as possible, in particular, before we check for header presence
(as -stdlib=libc++ modifies header lookup rules). Otherwise we can find a header
at configure time (w/o -stdlib=libc++) but fail to find it at build time
(with -stdlib=libc++). See PR18569 for more details.

It missed include/llvm/Target. Could I avoid GLOB_RECURSE anyways? :(
FYI, I intended to prune ${LLVM_MAIN_INCLUDE_DIR} in TableGen.cmake in r200150.

This will disable -ffunction-sections in older versions of Clang where it
breaks build of sanitizer runtime library.

LLVM_REQUIRES_EH implies LLVM_REQUIRES_RTTI. It is as same behavior as Makefile.rule's.
llvm/examples/ExceptionDemo is affected. (It was built with -fno-rtti.)
For MSVC, Remove flags like "/EHsc /GR" in HandleLLVMOptions, or CL.EXE complains with flags like "/GR /GR-".
llvm_update_compile_flags() updates source file property if the target contains *.c.
COMPILE_FLAGS in target properties affects both C++ and C!
LLVM_NO_RTTI is deprecated. It was introduced by me and was my mistake.

With this tweaks, also unittests are compiled with -ffunction-sections.
It's hard to control contextual CMAKE_CXX_FLAGS. We should get rid of twiddling it as possible.

ADDITIONAL_HEADERS is intended to add header files for IDEs as hint.
For example:
add_llvm_library(LLVMSupport
Host.cpp
ADDITIONAL_HEADERS
Unix/Host.inc
Windows/Host.inc
)

In LLVM build tree, they points corresponding INTDIR.
In Clang standalone tree, they points external dir (llvm-config's --bindir and --libdir).

The generation of the native_export_file end up in
several different makefiles. All those makefiles
write the same file, but can be executed concurrently...
and bad things happen!

option with the others in the top level CMakeLists, and put the check in
HandleLLVMOptions. This will also let it be used from the standalone
Clang builds.

This is needed to support the addition of tests for clang loadable plugins.
In clang, plugins are built as modules (bundles on OS X) rather than dynamic
libraries (dylib) so the build system needs to inform lit of the actual
file extension in use, typically '.so' on Unix and '.dll' on Windows.
(LLVM itself should probably switch to this scheme to fix PR14903 once and for
all.)
No change in build output or functionality intended.

Plugins need to go in build/Debug/lib as well (rather than build/lib/Debug).
Also, fix the SHLIBDIR path for Xcode, which by default includes Xcode build
settings rather than a simple %(build_mode)s parameter.

When building Clang separately from LLVM with CMake, one should set
the path of llvm-config via the cache variable LLVM_CONFIG.

We have been seeing nasty directory layout with CMake multiconfig, such as,
bin/Release/clang.exe
lib/clang/3.x/...
lib/Release/clang/3.x/.. (duplicated)
Move the layout similar to autoconf's;
Release/bin/clang.exe
Release/lib/clang/3.x/...
Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?
Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.
