Eric Fiselier 0913ca1978 Implement P0768r1: Library support for the Spaceship Operator.
this patch adds the <compare> header and implements all of it
except for [comp.alg].

As I understand it, the header is needed by the compiler in
when implementing the semantics of operator<=>. For that reason
I feel it's important to land this header early, despite
all compilers lacking support.

Eric Fiselier acc32abb11 Touch up tests for new <version> header; fix module.modulemap.
This patch does some housekeeping for the new <version> header.
It adds it to the module.modulemap, and the double_include.sh.cpp test.

Additionally it corrects the // UNSUPPORTED options for the libc++
specific test. The header needs to compile under C++03 to support
modules, and it should compile under all available compilers.

Eric Fiselier a016efb1dc [Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows
Summary:
This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning.
This patch changes libc++ to use `#pragma push_macro`  to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.

Eric Fiselier ea96891fb4 Re-add <experimental/coroutine> to the module map.
The original issues were caused because <experimental/coroutine>
didn't correctly #ifdef out enough of the header, which caused incomplete
types to be used.

This patch fixes the `#if defined(__cpp_coroutines)` guard and re-adds
the headers to the module map.

It also uglifies some incorrectly non-reserved names.

Eric Fiselier cd71f447b7 [libc++] Tolerate presence of __deallocate macro
Summary:
On Windows the identifier `__deallocate` is defined as a macro by one of the Windows system headers. Previously libc++ worked around this by `#undef __deallocate` and generating a warning. However this causes the WIN32 version of `__threading_support` to always generate a warning on Windows. This is not OK.

This patch renames all usages of `__deallocate` internally as to not conflict with the macro.

Reverting because I didn't properly test this patch. Although it's probably
correct to add a stdbool_h module I thought the change fixed more than it did.
I'll re-commit after more investigation.

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.

Eric Fiselier 198955536e Allow libc++ to use modules in C++03.
Libc++ internal uses <atomic> in C++03 code but the module map forbids its use.
This causes the libc++ 'std' module to fail to build in C++03.

This patch removes the requirement to fix this issue.

Eric Fiselier 074d46d55f [libcxx] Implement locale.h to fix modules build
Summary:
Because `locale.h` isn't part of the libc++ modules the class definitions it provides are exported as part of `__locale` (since it happens to be build first). This breaks `<clocale>` which exports `std::lconv` without including `<__locale>`.

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

Saleem Abdulrasool 8e5ce33193 Handle function name conflicts in _LIBCPP_MSVCRT mode
Visual Studio's SAL extension uses a macro named __deallocate. This macro is
used pervasively, and gets included through various different ways. This
conflicts with the similarly named interfaces in libc++. Introduce a undef
header similar to __undef_min_max to handle this. This fixes a number of errors
due to the macro replacing the function name.

Nico Weber 28d692d30e Mark module atomic as cplusplus11.
With clang, the header atomic requires __has_feature(cxx_atomic), which is only
true in c++11 mode. Because of this, when using modules in c++98 with libc++
compilation of the std module would fail without this change, PR21002.

(With gcc, only gcc4.7+ is needed, no c++11. But gcc doesn't have modules yet,
and the module.modulemap language can't express things like "this is only
required if the compiler is clang". If gcc gets module support, we'd probably
have a module.modulemap file for each compiler that libc++ supports?)
