Before this patch, the CMake build assumed LIT_EXECUTABLE pointed
to a Python script, not an executable. If you were to pass in an
executable, such as the result of py2exe on lit.py, the build would
fall over.
With this patch, the CMake build assumes LIT_EXECUTABLE is an
executable. You can continue setting it to lit.py, but it will
now use its shebang to find a Python interpreter.

Summary:
Currently to run tests in tree you need to symlink the lit.site.cfg file generated by the cmake build into the source tree, and teach your VCS to ignore it.
This allows the user to specify where to find the lit.site.cfg file two different ways:
* lit_site_config lit parameter
* LIT_SITE_CONFIG enviroment variable.
example usage:
```
lit -sv --param=libcxx_site_config=path/to/libcxx-build/test/lit.site.cfg path/to/tests
```
Or
```
export LIBCXX_SITE_CONFIG=path/to/libcxx-build/test/lit.site.cfg
lit -sv path/to/tests
```
The command line parameter will override the environment variable.
If neither options are present a warning is issued and the `lit.cfg` file is loaded directly.

Currently hacks must be used in to configure and build libc++ without threads
when using CMake. This patch adds CMake options to enable/disable building with
threads and a monotonic clock.
This patch also propagates the configuration information to lit so the tests
are properly configured as well.
llvm-svn: 223591
Summary:
In order to gather more information about testsuite results these flags should be added to LIT's default args.
These new switches were recently added to LIT. It been more than two weeks since both switches were added.
I think its time we add these to our LIT flags.

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.
