This makes them consistent (many comments already used uppercase).
The special REQUIRES, UNSUPPORTED, and XFAIL comments are excluded from this change.

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.

attribute.
This is needed because older versions of libc++ do not have these
operators. If users target an older deployment target and try to compile
programs in which these operators are explicitly called, the compiler
will complain.
The following is the list of minimum deployment targets for the four
OSes:
macosx: 10.13
ios: 11.0
tvos: 11.0
watchos: 4.0

This patch fixes the test failures and unexpected passes that occur
when testing against GCC 7. Specifically:
* don't mark __gcd as always inline because it's a recursive function. GCC diagnoses this.
* don't XFAIL the aligned allocation tests. GCC 7 supports them but not the -faligned-allocation option.
* Work around gcc.gnu.org/PR78489 in variants constructors.

Libc++ doesn't provide its own definitions of new/delete on Windows,
instead using the versions provided by VCRuntime. However VCRuntime
does not yet implement aligned new/delete so these tests fail.
It might be possible for libc++ to provide its own definitions only
for aligned new/delete as long as MSVC doesn't provide it. However
before this can be done libc++ needs to figure out how to implement
std::get_new_handler.

Libc++ is used as a system library on macOS and iOS (amongst others). In order
for users to be able to compile a binary that is intended to be deployed to an
older version of the platform, clang provides the
availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_
that can be placed on declarations to describe the lifecycle of a symbol in the
library.
See docs/DesignDocs/AvailabilityMarkup.rst for more information.

Summary:
This patch implements the library side of P0035R4. The implementation is thanks to @rsmith.
In addition to the C++17 implementation, the library implementation can be explicitly turned on using `-faligned-allocation` in all dialects.

This patch addresses the following issues in the test suite:
1. Move "std::bad_array_length" test from std/ to libcxx/ test directory
since the feature is not a part of the standard.
2. Rename "futures.tas" test directory to "futures.task" since that is the
correct stable name.
3. Move tests for "packaged_task<T>::result_type" from std/ to libcxx/
test directory since the typedef is a libc++ extension.

Quite a few libcxx tests seem to follow the format:
#if _LIBCPP_STD_VER > X
// Do test.
#else
// Empty test.
#endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.

Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.
This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

Summary:
This patch does 2 main things:
1. Enable sized delete if the feature test macro `__cpp_sized_deallocation` is enabled.
2. Rework and cleanup all of the sized delete tests.
Test Plan:
The sized delete replacement tests are now split into 4 files:
1. sized_delete11.pass.cpp: Ensure overriding sized delete in C++11 has no effect.
2. sized_delete14.pass.cpp: Test overriding sized delete in C++14 and ensure it is called. This test fails on clang and GCC < 5.1.
3. size_delete_calls_unsized_delete_.pass.cpp: Test that the default sized delete calls unsized delete.
4. sized_delete_fsizeddeallocation.pass.cpp: Test overriding sized delete when -fsized-deallocation is passed. This test should pass on clang and GCC >= 5.1
I have also removed a lot of cruft from the old tests. They no longer replace the new handler and tests that it is called for bad allocations.
