Eric Fiselier 78fdf2d0f5 [libcxx] Add code coverage configuration to CMake and LIT.
Summary:
This patch adds configuration to CMake and LIT for running the libc++ test-suite to generate code coverage.

To use code coverage use following instructions.

* Find the clang resource dir using `$CXX -print-search-dirs`. Let <library-dir> be the first library search directory.
* `cmake <regular-options> -DLIBCXX_GENERATE_COVERAGE=ON -DLIBCXX_COVERAGE_LIBRARY=<library-dir>/lib/<platform>/libclang_rt.profile.a <source>`
* `make cxx`
* `make check-libcxx`
* `make generate-libcxx-coverage`


The reason I want this patch upstreamed is so I can setup a bot that generates code coverage and posts in online for every revision.

Eric Fiselier 0357171f1c [libcxx] Add support for linking libc++ against a static ABI library.
Summary:
This patch add the CMake option `LIBCXX_ENABLE_STATIC_ABI_LIBRARY` which, when enabled, will link libc++ against the static version of the ABI library.

Eric Fiselier d2852b69ce [libcxx] Move to using libc++abi2.exp as the default symbol list for libc++
Summary:
libc++abi2.exp should be used whenever `cxxabi.h` defines `_LIBCPPABI_VERSION`. This macro was added to libc++abi in 2012 in r149632. For this reason we should use libc++abi2.exp as default unless otherwise specified.

Also when building against an in-tree libc++abi we definitely want to use libc++abi2.exp.

I would love to know what OSX was the last to use libc++abi.exp but I can only test on 10.9.

Chandler Carruth 64be05a873 [cmake/multilib] Teach libc++'s CMake build to support multilib libdir
suffixes like 'lib64' or 'lib32'.

This support is currently very rhudimentary. We define a variable
LIBCXX_LIBDIR_SUFFIX. In a standalone build of libc++ this can be
directly set as a cached variable to control the multilib suffix used.
When building libc++ within a larger LLVM build, it is hard wired to
whatever LLVM libdir suffix has been selected. If this doesn't work for
someone, just let me know. I'm happy to change it.

This is essentially new functionality for libc++ so I don't expect it to
have any impact for folks until they start setting these variables.
However, I know libc++ is built in a diverse set of environments so just
let me know if this causes you any problems.

Eric Fiselier 5aedca96d5 [libcxx] Refactor CMakeLists.txt handling of compile and link flags to suppress warnings.
Summary:
Currently we have 5 variables that are used to specify options for building libcxx
1. `LIBCXX_CXX_FEATURE_FLAGS`
2. `LIBCXX_CXX_WARNING_FLAGS`
3. `LIBCXX_CXX_REQUIRED_FLAGS`
4. `compile_flags` (in libcxx/lib)
5. `link_flags` (in libcxx/lib)

The first three all get put into `CMAKE_CXX_FLAGS`. 
This changes the way flags are handled by only using 3 different options:

1. `LIBCXX_CXX_FLAGS` - general compile and link flags.
2. `LIBCXX_COMPILE_FLAGS` - compile only flags.
3. `LIBCXX_LINK_FLAGS` - link only flags.

This patch also removes the warning about `-nostdinc++` being unused during linking.

Eric Fiselier a63c149ceb [libcxx] Redo adding support for building and testing with an ABI library not along linker paths
Summary:
This is the second attempt at allowing for the use of libraries that the linker cannot find. The first attempt used `CMAKE_LIBRARY_PATH` and `find_library` to select which ABI library should be used. There were a number of problems with this approach:

- `find_library` didn't work with cmake targets (ie in-tree libcxxabi build)
- It wasn't always possible to determine where `find_library` actually found your library.
- `target_link_libraries` inserted the path of the ABI library into libc++'s RPATH when `find_library` was used.
- Linking libc++ and it's ABI library is a special case. It's a lot easier to keep it simple. 

After discussion with @cbergstrum a new approach was decided upon.
This patch achieve the same ends by simply using `LIBCXX_CXX_ABI_LIBRARY_PATH` to specify where to find the library (if the linker won't find it). When this variable is defined it is simply added as a library search path when linking libc++. It is a lot easier to duplicate this behavior in LIT. It also prevents libc++ from being linked with an RPATH.
