Louis Dionne 94104b1b6b [libcxx] Fix XFAILs for aligned allocation tests
In r339743, I marked several aligned allocation tests as downright
unsupported on macosx in an attempt to unbreak the build. It turns
out that marking them as unuspported whenever we're on OS X is way
too coarse grained. This commit marks the tests as XFAIL with more
granularity.

The test is trying to avoid saying aligned_alloc on Windows' UCRT, which does not (and can not) implement aligned_alloc. However, it's testing for c1xx, meaning clang on Windows will fail this test when using the UCRT.

Louis Dionne 7c6baa2184 [libcxx] Fix XFAILs for aligned allocation tests on older OSX versions
Summary:
Since r338934, Clang emits an error when aligned allocation functions are
used in conjunction with a system libc++ dylib that does not support those
functions. This causes some tests to fail when testing against older libc++
dylibs. This commit marks those tests as UNSUPPORTED, and also documents the
various reasons for the tests being unsupported.

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 107d6d6845 Use DoNotOptimize to prevent new/delete elision.
The new/delete tests, in particular those which test replacement
functions, often fail when the optimizer is enabled because the
calls to new/delete may be optimized away, regardless of their side-effects.

This patch converts the tests to use DoNotOptimize in order to prevent
the elision.

Eric Fiselier decf22e50f Fix most GCC test failures.
This patch fixes almost all currently failing tests when
using GCC ToT.

The specific changes are:

(A) Workaround gcc.gnu.org/PR83921 which rejects variables w/o initializers
in constexpr contexts -- even when the variable is an empty class. This
bug has been worked around at all callsites by adding an initializer.
Additionally a new test, constexpr_init.pass.cpp, has been added to
test that Clang doesn't suffer from these bugs.

(B) Fix streambuf.assign/swap.pass.cpp. This test was never actually
calling the swap method as intended. In fact, the swap function it
intended to call was ill-formed when instantiated. GCC diagnosed
this ill-formedness w/o needing an instantiation.

(C) size_delete11.pass.cpp was fixed by adding c++2a to the list of
unsupported dialects.

Eric Fiselier 6b3e48b46a Fix nodiscard failure tests on compilers w/o -verify.
Previously .fail.cpp tests for nodiscard were run with -Wunused-result
being a warning, not an error, when the compiler didn't support -verify.

When -verify isn't enabled this change judiciously adds -Werror=unused-result
when to only the failure tests containing the // expected-error string for nodiscard.

As a drive-by change, this patch also adds a missing // UNSUPPORTED: c++2a to
a test which was only supposed to run in C++ <= 11.

Shoaib Meenai 492d7134f3 [libc++] Support Microsoft ABI without vcruntime headers
The vcruntime headers are hairy and clash with both libc++ headers
themselves and other libraries. libc++ normally deals with the clashes
by deferring to the vcruntime headers and silencing its own definitions,
but for clients which don't want to depend on vcruntime headers, it's
desirable to support the opposite, i.e. have libc++ provide its own
definitions.

Certain operator new/delete replacement scenarios are not currently
supported in this mode, which requires some tests to be marked XFAIL.
The added documentation has more details.

Akira Hatanaka 539cb66bea Revert "[libcxx] Annotate c++17 aligned new/delete operators with availability"
This reverts commit r306310.

r306310 causes clang to reject a call to an aligned allocation or
deallocation function if it is not implemented in the standard library
of the deployment target. This is not the desired behavior when users
have defined their own aligned functions.
