Summary:
In the CHERI clang compiler __output and __input are keywords and therefore
we can't compile libc++ with our compiler.

r313500 added a fix for undefined "___cxa_deleted_virtual" symbol.
Previous libcxx versions don't have the fix and corresponding test
should be failing.

This patch changes the test suite to attempt and prefer -std=c++17 over
-std=c++1z. It also fixes the REQUIRES and UNSUPPORTED lit markers
to refer to c++17 over c++1z.

LWG 3013 points out that the constructors and increment members
of the directory iterators need to allocate, and therefore cannot
be marked noexcept.
It also points out that `is_empty` and `copy` likely need to allocate
as well, and as such can also not be noexcept.
This patch speculatively implements the resolution removing noexcept,
because libc++ does indeed have the possibility of throwing on allocation
failure.

The guts of the increment method for recursive_directory_iterator
was failing to pass an error code object to calls to status/symlink_status,
which can throw under certain conditions.
This patch fixes the issues by correctly propagating the error codes.
However the noexcept still needs to be removed from the signature, as
mentioned in LWG 3014, but that change will be made in a separate commit.

Summary:
The constructors `vector(Iter, Iter, Alloc = Alloc{})` and `assign(Iter, Iter)` don't correctly perform EmplaceConstruction from the result of dereferencing the iterator. This results in them performing an additional and unneeded copy.
This patch addresses the issue by correctly using `emplace_back` in C++11 and newer.
There are also some bugs in our `insert` implementation, but those will be handled separately.
@mclow.lists We should probably merge this into 5.1, agreed?

I *did* try to check that such kind of an issue was not introduced
by the rL315874, but clearly i failed to finish verification.

Previously this broke the builders, when D38101 was committed.
Silence the warning so that it can be re-landed.

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.

This warning "structure was padded due to alignment specifier" says
that the compiler is going to do exactly what you asked it to do.
It's triggered by the tests for over-aligned dynamic memory allocation.

After speaking with the libcxx owners, they agreed that this is
a bug in the bot that needs to be fixed by the bot owners, and
the CMake changes are correct.

This reverts commit 4ad71811d45268d81b60f27e3b8b2bcbc23bd7b9.
There is a bot that is checking out libcxx and lit with nothing
else and then running lit.py against the test tree. Since there's
no LLVM source tree, there's no LLVM CMake. CMake actually
reports this as a warning saying unsupported libcxx configuration,
but I guess someone is depending on it anyway.
