Summary:
The data files for any given test will be in the same directory as the
source with a file name that matches *.dat. To make these available to
tests running remotely (such as over adb or ssh), copy them into the
test's remote working directory.
Note that we will perform more copies than we actually need. The data
files in the directory may only be used by one of the tests, but will
be copied for all tests in the same directory.
This patch also moves the remote test binary into the working
directory (previously it was only invoked from the working directory
rather than existing in it).

We should probably be using this argument to find the data files for
the tests, but that isn't implemented yet.

The PrefixExecutor wasn't passing the exe_path down the chain, so the
command was overriding that, the work_dir was being passed as the
command, and so on.
I've cleaned up a few pylint issues while I was here.

Executors can be specified at configure time by using the -DLIBCXX_EXECUTOR=""
option. Examples include:
$ cmake <other_flags> -DLIBCXX_EXECUTOR="TimeoutExecutor(30,LocalExecutor())"
This runs individual tests with a maximum duration
$ cmake <other_flags> -DLIBCXX_EXECUTOR="SSHExecutor('hostname','username')"
This runs tests on a remote target, using scp to shuttle binaries to the
target, and ssh to invoke commands there.
$ cmake <other_flags> -DLIBCXX_EXECUTOR="PrefixExecutor('/path/to/run/script',LocalExecutor())"
This assumes the script knows how to copy run the executables passed to it,
and allows for the ultimate control. This is useful for running things
inside emulators like Valgrind & QEMU.
TODO: This doesn't claim to support ShTest tests yet, that will take a bit more
thought & finagling (I'm still not sure how to orchestrate copy-in for those cases.
I've also punted on what to do about tests that read data files. The testsuite
has several tests that need to read *.dat files placed next to them, and
currently those aren't copied over when using, say, an SSHExecutor. The
affected tests are:
libc++ :: std/input.output/file.streams/fstreams/filebuf.virtuals/pbackfail.pass.cpp
libc++ :: std/input.output/file.streams/fstreams/filebuf.virtuals/underflow.pass.cpp

libc++ :: std/localization/locales/locale.convenience/conversions/conversions.buffer/pbackfail.pass.cpp
libc++ :: std/localization/locales/locale.convenience/conversions/conversions.buffer/underflow.pass.cpp
Note: One thing to watch out for when using the SSHExecutor for cross-testing is
that you'll also want to specify a TargetInfo object (so that the host's
features aren't used for available-features checks and flags setup).

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.

Summary:
This patch adds a lit option to enable color diagnostics when either `--param=color_diagnostics` is passed to LIT or `LIBCXX_COLOR_DIAGNOSTICS` is present in the environment.
My only concern with this patch is that GCC and Clang take different flags and that only GCC 4.9 and greater support `-fdiagnostics-color=always`
Does anybody have objections to this going in?

Summary:
The requirement on the `Size` type passed to *_n algorithms is that it is convertible to an integral type. This means we can't use a variable of type `Size` directly. Instead we need to convert it to an integral type first. The problem is finding out what integral type to convert it to. `__convert_to_integral` figures out what integral type to convert it to and performs the conversion, It also promotes the resulting integral type so that it is at least as big as an integer. `__convert_to_integral` also has a special case for converting enums. This should only work on non-scoped enumerations because it does not apply an explicit conversion from the enum to its underlying type.

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.
