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.

This isn't actually used for anything, and is broken on Darwin
(currently causing build failures now that the triple is passed to aid
cross compiling). Rather than fix unused code, just remove it.

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).

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.
