Eric Fiselier daf21c3f69 Adjust libc++ test infastructure to fully support modules
This patch overhalls the libc++ test format/configuration in order to fully support modules. By "fully support" I mean get almost all of the tests passing. The main hurdle for doing this is handling tests that `#define _LIBCPP_FOO` macros to test a different configuration. This patch deals with these tests in the following ways:

1. For tests that define single `_LIBCPP_ABI_FOO` macros have been annotated with `// MODULES_DEFINES: _LIBCPP_ABI_FOO`. This allows the test suite to define the macro on the command line so it uses a different set of modules.
2. Tests for libc++'s debug mode (which define custom `_LIBCPP_ASSERT`) are automatically detected by the test suite and are compiled and run with modules disabled.

This patch also cleans up how the `CXXCompiler` helper class handles enabling/disabling language features.

NOTE: This patch uses `LIT` features which were only committed to LLVM today. If this patch breaks running the libc++ tests you probably need to update LLVM.

Shoaib Meenai fc6100c195 [libc++] Add _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS
It's useful to be able to disable visibility annotations entirely; for
example, if we're building libc++ static to include in another library,
and we don't want any libc++ functions getting exported out of that
library. This is a generalization of _LIBCPP_DISABLE_DLL_IMPORT_EXPORT.

Roger Ferrer Ibanez 4cb4b36aa2 Handle tests for noexcept that expect a false value
Under libcpp-no-exceptions, noexcept is trivially true. Some tests expect in
the usual setting to return false, so adjust them to expect true under
libcpp-no-exceptions.

Eric Fiselier 02460bac8b Choose better hash values for std::monostate and valueless variants.
Previously these hashes were 0 and -1 respectively. These seem like common
sentinel values and should be avoided to prevent needless collisions.

This patch changes those values to different arbitrary numbers, which should
hopefully cause less collisions. Because I couldn't help myself I choose the
fundamental constants for gravity and the speed of light.

This patch implements `locale.h` to fix this issue, it also adds support for testing libc++ with modules.

Eric Fiselier 194e81f620 Allow using libsupc++ with LIBCXX_ENABLE_STATIC_ABI_LIBRARY. Patch from Michael Daniels.
The code cannot currently link when using libsupc++ with the
LIBCXX_ENABLE_STATIC_ABI_LIBRARY option.

This change ifdef's out the the destructor and 'what' function for
bad_array_length and bad_array_new_length when GLIBCXX is defined.
The constructors that are left in are the only functions not being provided by
libsupc++ itself, and follows the same pattern that was used to ifdef bad_alloc.

Testing was done on a Linux x86_64 host using GCC 5.4 and libc++ from ToT.
I see no change to the test results when using libsup++ or libstdc++ without
LIBCXX_ENABLE_STATIC_ABI_LIBRARY. When using libsupc++ with
LIBCXX_ENABLE_STATIC_ABI_LIBRARY it will now build and test results are the
same as those without the option specified.

sample() isn't specified with a reproducible algorithm, so expecting

In test_small_population(), we're guaranteed to get all of the elements,

forward, we're guaranteed stability (and can therefore test equal()).
Otherwise, we can only test is_permutation(). (As it happens, both libcxx

captures the semantics better, and also allows us to get rid of the
`_WIN32` check in `include/new`. No functional change.

Justin Lebar 20cb820880 [libcxx] Mark xonstexpr-fns.pass.cpp as XFAIL: gcc.
This fails with gcc because __builtin_isnan and friends, which
libcpp_isnan and friends call, are not themselves constexpr-evaluatable.

Eric Fiselier 7004d6664e Add .clang-format to libc++
Adding a Clang Format file to libc++ and which style it should use has been
discussed a couple of times. This patch finally adds a .clang-format file
which specifies LLVM styles.

Personally I dislike how the LLVM style handles much of the meta-programming
in libc++. However the general consensus was that libc++ should prefer the
LLVM style and make adjustments where needed.

Note that using clang-format on changes is not required, especially for
changes within the headers. However formatting tests should be encouraged.

Justin Lebar 2d3482287b [CUDA] Mark __libcpp_{isnan,isinf,isfinite} as constexpr.
Summary:
This makes these functions available on host and device, which is
necessary to compile <complex> for the device.

Vedant Kumar 50d161ce0f Revert "P0503R0, adopted in Issaquah, rewords some requirements on nullptr_t and istream_iterator. No code changes were needed, but I updated a few tests. Also resolved P0509 and P0521, which required no changes to the library or tests."
This reverts commit r286884, because it breaks the Xcode 7 builders:

Stephan T. Lavavej 49188b1d3c [libcxx] [test] D26624: Fix bucket_count() assumptions.
With a max_load_factor of 1.0, the only guarantee is that
bucket_count() >= size(). (Note: setting max_load_factor without
rehashing isn't supposed to affect this, because setting
max_load_factor is currently specified to be constant time.)
