Eric Fiselier bb19141779 Add special case handling of linux target triples that do not contain `-gnu`.
For targets that end it `redhat-linux` and `suse-linux` manually add the `-gnu`
section of the target since `linux-gnu` is needed in the testsuite.

This patch also moves the removal of minor and patchlevel numbers from OSX
triples to be handled when deducing the triple instead of when adding available
features.

Eric Fiselier 460b224ef9 Change uses of `sys.platform == 'linux2' to `sys.platform.startswith('linux')
Although the current method is valid up till python 3.3 (which is not supported)
this seems to be a clearer way of checking for linux and moves the tests towards
python 3 compatibility.

Eric Fiselier 062e6ee121 Add -ldl to libc++ tests when sanitizers are used.
Clang 3.6 no longer links the sanitizer runtime library dependancies when
-nodefaultlibs is used. This patch manually links in a missing dependancy.

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.

Eric Fiselier 6f9da55c0f [libcxx] Add support for building and testing with an ABI library not along linker paths
Summary:
This patch adds support for building/testing libc++ with an ABI library that the linker would not normally find.

- `CMAKE_LIBRARY_PATH` is used to specify the list of search directories.
- The ABI library is now found using `find_library` instead of assuming its along the linker's search path.
- `CMAKE_LIBRARY_PATH` is passed to our LIT config as `library_paths`.
- For each path in `library_paths` the following flags are added `-L<path> -Wl,-rpath -Wl,<path>`

Some changes in existing behavior were also added:
- `target_link_libraries` is now passed the ABI library file instead of the library name. Ex `target_link_libraries(cxx "/usr/lib/libc++abi.so")` vs `target_link_libraries(cxx "c++abi")`.
- `-Wl,-rpath -Wl,<path>` is now used on OSX to link to libc++ instead of env['DYLD_LIBRARY_PATH'] if `use_system_lib=False`.

Justin Bogner 2cfd1fed21 test: Make it possible to opt in to use_clang_verify per test
This modifies the use_clang_verify parameter I added in r217009 to
only apply to tests that specifically ask for it via // USE_VERIFY.
This allows us to incrementally convert tests, but start enjoying the
benefits right away.

Suggested by Eric Fiselier in code review.

Justin Bogner 33a2a2ed1a test: Allow using clang -verify for failures rather than exit 1
Currently, failure tests work by checking that compilation exits 1.
This can lead to tests that fail for the wrong reason, so it'd be
preferable to convert them to check for specific errors.

This adds use_clang_verify parameter that runs failure tests using
clang's -verify flag. I'll convert some tests in subsequent commits,
and once all of the tests are converted we should key this on whether
cxx_under_test is clang.

I've also converted one of the unique.ptr tests, since it's the one
that motivated the idea of using clang -verify when possible in the
review of r216317.

Dan Albert ae2526b4cd Refactor lit.cfg.
The purely imperative format of the configuration performed in lit.cfg
was making merge conflicts with changes I have for Android an
unbelievable pain in the ass. I've moved all of the configuration into a
Configuration class, with each piece of configuration happening in a
different method. This way I can avoid merge conflicts, and any new
features that get added (as have been done with the sanitizers, the -std
flag, etc.) can be easily applied to Android as well.

Eric Fiselier 0058c80cc7 [libcxx] Add support for LLVM_USE_SANITIZER to libcxx when being built standalone and in-tree
Summary:
This patch adds support for LLVM_USE_SANITIZER when being built in-tree and standalone. 

This patch does the following things:
1. define the LLVM_USE_SANITIZER option to "" when being built standalone. This also helps show we support it.
2. Translate LLVM_USE_SANITIZER when standalone in a very similar way done in llvm/cmake/HandleLLVMOptions.cmake.
3. Add config.llvm_use_sanitizer to lit.site.cfg.in
4. Add code to translate config.llvm_use_sanitizer's value into the needed compile flags in lit.cfg.

Currently lit.cfg assumes that that the compiler supports '-fno-omit-frame-pointer' while CMakeLists.txt actually checks to see if its supported. We could pass this information to lit but I'm not sure its needed.

Eric Fiselier 1b44db22c6 [libcxx] Update the way the -std= flag is chosen by CMake and LibcxxTestFormat
Summary:
This patch does two things:
CMake Update:
  - Add compiler flag checks for -std=c++11 and -std=c++1y and remove check for -std=c++0x.
  - Add configuration option LIBCXX_ENABLE_CXX1Y to prevent/allow -std=c++1y from being chosen as the std version. LIBCXX_ENABLE_CXX1Y is set to OFF by default.
  - if LIBCXX_ENABLE_CXX1Y is enabled then set LIBCXX_STD_VERSION to c++1y and fail if the compiler does not support -std=c++1y
  - If c++1y is not enabled then use c++11 and fail if the compiler does not support c++11.

Lit Update:
  - Update lit.site.cfg.in to capture LIBCXX_STD_VERSION information as config.std.
  - Remove mentions of has_cxx0X configuration option.
  - Check for `--param std=X' passed to lit on the command line.
  - Choose the std for the tests either from command line parameter or (if it doesn't exist) the lit.site.cfg.

Dan Albert a85b27f6f7 Add locales to available_features for tests.
Linux has a lot of failures caused by not having support for certain
locales. Since these come out as a lot of noise in the test results,
have lit.cfg detect the presence of the various locales used in the
tests and add them to config.available_features as locale.LOCALE_NAME.

This patch also adds REQUIRES: locale.REQUIRED_LOCALE to every test that
I saw failing in this manner. We probably need to add more for all the
tests requiring en_US.UTF-8, but we can do that on an as-needed basis.

One thing that concerns me is how many tests get skipped because of
missing locales (especially in regex/). We should make a point of
splitting up any tests that test default behavior _and_ behavior under a
given locale so that we aren't losing coverage for default behavior.

lit.py: <string>:230: note: inferred use_system_lib as: False

cxx_abi is geting set to None, and the lit script errors out shortly after
that.  This patch changes the default of cxx_abi from None to 'libcxxabi'.
This is likely not the right way to fix this problem.  However it gets the
buildbot running again.  Improvements to this fix are welcome.

Peter Collingbourne 26dd09e57f Make it possible to link against libstdc++ as well as libsupc++ with CMake.
Linking against libstdc++, rather than libsupc++, is probably better
for people who need to link against clients of libstdc++.  Because
libsupc++ is provided only as a static library, its globals are not
shared between the static library and the copy linked into libstdc++.
This has been found to cause at least one test failure.

This also removes a number of symbols which were multiply defined
between libstdc++ and libc++, only when linking with libstdc++.
