Introduce a cmake LLVM_ENABLE_LIBCXX build parameter to compile using libc++ instead of the system default 

Summary:
This parameter is required to build C++11 projects (like lld or lldb) on OS X as the default STL does not provide c++ classes.

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.

[CMake][VS][XCode] Restruct the output directory layout more comfortable, ${BINARY_DIR}/${BUILD_MODE}/(bin|lib)

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.

Also add leading spaces to the LINK_FLAGS setters, since that's what the cmake
folks recommend: http://www.cmake.org/pipermail/cmake/2012-October/052399.html

[CMake] add_llvm_symbol_exports: Use ${native_export_file} instead of equivalent constant "symbol.*', since it is defined.

r198153 fixed the msvs bot problem, but broke a msysgit bot. This change
hopefully makes both variants happy.

The windows ninja build is now green, but msvs is still unhappy. Maybe that's
because the .def file was passed when building LTO_static, so only pass
symbol lists for shared libraries.

The current quoting is stripped by cmake, try quoting more.

llvm-svn: 198143

The command that cmd.exe is complaining about is:
cmd.exe /c cd /D C:\bb-win7\cmake-clang-i686-mingw32\build\tools\lto && cmake -E echo EXPORTS > symbol.def && type C:/bb-win7/cmake-clang-i686-mingw32/llvm-project/llvm/tools/lto/lto.exports >> symbol.def

Maybe quoting the filename helps.

`type` can't read from stdin.

$ needs to be written $$ in makefiles, but not in cmakefiles.

The cmake build didn't support EXPORTED_SYMBOL_FILE. Instead, it had a
Windows-only implementation in tools/lto/CMakeLists.txt, a linux-only
implementation in tools/gold/CMakeLists.txt, and a darwin-only implementation
in tools/clang/tools/libclang/CMakeLists.txt.

This attempts to consolidate these one-offs into a single place. Clients can now
just set LLVM_EXPORTED_SYMBOL_FILE and things (hopefully) Just Work, like in
the make build.

This changes Clang standalone builds so that clang-tblgen lives in
clang/build/bin instead of llvm/build/bin, and so that with the Xcode
generator it's in clang/build/bin/Debug instead of llvm/build/bin/Debug/Debug/.
Yes, really.

[CMake] Introduce LLVM_RUNTIME_OUTPUT_INTDIR and LLVM_LIBRARY_OUTPUT_INTDIR to reduce references to CMAKE_CFG_INTDIR.

Each of them forms like;
  ${CMAKE_BINARY_DIR}/bin/${CMAKE_CFG_INTDIR}
  ${CMAKE_BINARY_DIR}/lib/${CMAKE_CFG_INTDIR}

[CMake] add_lit_target: Let lit.site.cfg free from "--param build_mode" on single configuration builds, like autoconf build.

I think, in principle, intrinsics_gen may be added explicitly.
That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen.
Almost all source files depend on both CommonTaleGen and intrinsics_gen.

Explicit add_dependencies() have been pruned under lib/Target.

add_public_tablegen_target adds *CommonTableGen to LLVM_COMMON_DEPENDS.
LLVM_COMMON_DEPENDS affects add_llvm_library (and other add_target stuff) within its scope.

In some case, it may be required to build LLVM in C++11 mode, as some the subprojects (like lldb) requires it.

This mimics the autoconf behaviour.

However, given the discussions on the switch to C++11 of the codebase, this behaviour should evolve to default to C++11 with some checks of the compiler capabilities.

llvm-svn: 195727

Reid pointed out we already have LLVM_USE_CRT_{buildtype} to set it.

for release builds.

This is a follow-up to r194589. Aaron pointed out that building
libraries with /MT and using them in an application that uses a
different run-time library can be a bad idea.

Move the option to build with /MT behind a CMake option so it can be
turned on selectively, such as when building the toolchain installer.
