he following snippet doesn't build when using gcc and libc++:
#include <string>
void f(const std::string& s) { s.begin(); }
#include <vector>
void AppendTo(const std::vector<char>& v) { v.begin(); }
The problem is that __wrap_iter has a private constructor. It lists vector<>
and basic_string<> as friends, but gcc seems to ignore this for vector<> for
some reason. Declaring vector before the friend declaration in __wrap_iter is
enough to work around this problem, so do that. With this patch, I'm able to
build chromium/android with libc++. Without it, two translation units fail to
build. (iosfwd already provides a forward declaration of basic_string.)
As far as I can tell, this is due to a gcc bug, which I filed as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64816.
Fixes PR22355.

Summary:
This patch allows the use of LIT's ShTest format in the libc++ test suite. ShTests have the suffix '.sh.cpp'. It also introduces a series of other changes. These changes are:
- More functionality including parsing test metadata has been moved into LIT.
- LibcxxTestFormat now supports multi-part suffixes.
- the `CXXCompiler` functionality has been used to shrink the size of LibcxxTestFormat.
- The recursive loading of the site config has been turned into `libcxx.test.config.loadSiteConfig` so it can be used with libc++abi.
- Temporary files are now created in the build directory of libc++. This follows how it is down in ShTest.
- `not.py` was added as a utility executable that mirrors the functionality of LLVM's `not` executable.
- The first ShTest test was added under test/libcxx/double_include.sh.cpp

This patch addresses some comments on http://reviews.llvm.org/D7019.
- Move compiler.py to test/libcxx from test/libcxx/test.
- Make CXXCompiler.target None by default.
- Use `{}` instead of `dict()` to initialize an empty dict.
- Pass the -fsanitize options to both the compile and link commands.

Summary:
This adds a compiler utility class that handles generating compile commands and running them. Instead of having to pass the compiler path and 3 groups of flags between the configuration and the test format this allows us to just pass the compiler object.

When 'no_default_flags' is true only flags passed using '--param=compile_flags'
and '--param=link_flags' will be used when compiling the tests. This option
can be used to run the test suite against libstdc++ and helps with all
unusual test suite configurations.
NOTE: sanitizer flags are still added when '--param=use_sanitizer' is used even
if '--param=no_default_flags' is given.

Summary:
I've moved the bulk of `lit.cfg` into `test/libcxx/testconfig.py` and
`test/libcxx/testformat.py`. All that remains in `lit.cfg` is the
logic to discover lit.site.cfg if lit.cfg was run directly, and the
logic for loading configuration variants.
The configuration variant flow has changed with this patch. Rather
than instantiating an object of type `<VARIANT>Configuration`, we now
instatiate an object of type `Configuration` that was loaded from the
module `<VARIANT>.testconfig.py`.
This has to be done on a per-project basis rather than in LIT itself
because LIT doesn't actually know where the real test directory is,
only where the site configuration is (which is usually in the output
directory). It's simple enough to do though, so it's fine to require
each project to do it themselves.
I also cleaned up all the pylint issues while I was here, which was
mostly just a matter of fixing long lines.

Clean up some copy pasta while I'm here (someone added a return
statement to a void function).

The SFINAE on the function __mu(Fn, Args...) that evaluates nested bind
expressions always tries to deduce the return type for Fn(Args...) even when Fn
is not a nested bind expression. This can cause hard compile errors when the
instantation of Fn(Args...) is ill-formed. This patch prevents the instantation
of __invoke_of<Fn, Args...> unless Fn is actually a bind expression.

Summary:
MSAN and ASAN also replace new/delete which leads to a link error in these tests. Currently they are unsupported but I think it would be useful if these tests could run with sanitizers.
This patch creates a support header that consolidates the new/delete replacement functionality and checking.
When we are using sanitizers new and delete are no longer replaced and the checks always return true.

Summary:
In order to fully replace the testit script we need to update LIT so it provides the same functionality.
This patch adds a number of different configuration options to LIT to do that. It also adds documentation for all of the command line parameters that LIT supports.
Generic options added:
- `libcxx_headers`
- `libcxx_library`
- `compile_flags`
Generic options modified:
- `link_flags`: Changed from overriding the default args to adding extra args instead (to match compile flags)
- `use_sanitizer`: Renamed from `llvm_use_sanitizer`
Please see the added documentation for more information about the switches. As for the actual documentation I'm not sure if it should be kept in libc++ forever since it adds an undue maintenance burden, but I think it should be added for the time being while the changes are new. I'm verify unskilled with HTML so if the documentation needs any changes please let me know.
Hopefully this will kill testit.
