This is necessary for from-scratch configurations to support the 32-bit

Now that Lit supports regular expressions inside XFAIL & friends, it is
much easier to write Lit annotations based on the triple.

Summary:
If we are on c++03 mode for some reason, and __builtin_va_copy is
available, then use it instead of error out on not having va_copy
in 03 mode.

This is required to run the tests under any configuration that uses
additional_features using a from-scratch config. That is the case of
e.g. the Debug mode (which uses LIBCXX-DEBUG-FIXME) and the tests on
Windows.
The various design docs have been moved to RST, and the linked blog post
does not apply anymore since libc++ is the default library used by Clang
on Apple platforms.
While we can debate on the value of passing by const value, there is no
arguing that it's confusing to do so in some circumstances, such as when
marking a pointer parameter as being const (did you mean a pointer-to-const?).
This commit fixes a few issues along those lines.
The __search helper function was once split into __functional for circular
dependency reasons, however this is not an issue anymore now that we have
finer grained headers.
Before this patch, Lit parameters that were set as a result of CMake
options were not made available to from-scratch configs. This patch
serializes those parameters into the generated lit config file so that
they are available to all configs.

This patch is to fix 2 libcxx test cases, test cases assumed 'a' > 'A' which is not case in z/OS platform on ebcdic mode, modified test cases to compare between upper letters or lower letters, or digits so ordering will be true for all platform.

With the STL containers, I didn't enable move operations in C++03 mode
because that would change the overload resolution for things that today
are copy operations. With iostreams, though, the copy operations aren't
present at all, and so I see no problem with enabling move operations
even in (Clang's greatly extended) C++03 mode.
Clang's C++03 mode does not support delegating constructors.

In typeinfo there is a reinterpret_cast between a uintptr_t and size_t. These are two integer types and therefore a reinterpret_cast is not right for this situation. It looks like it may have been copied and pasted from above in the file. An implicit cast works in it's place.

Moves:
* `std::move`, `std::forward`, `std::declval`, and `std::swap` into
`__utility/${FUNCTION_NAME}`.
* `std::swap_ranges` and `std::iter_swap` into
`__algorithm/${FUNCTION_NAME}`

Under the as-if rule, we can directly implement the array overload for
`std::swap`. By removing this circular dependency where `swap` is
implemented in terms of `swap_ranges` and `swap_ranges` is defined in
terms of `swap`, we can split them into their own headers. This will:
* limit the surface area in which Hyrum's law can bite us;
* force users to include the correct headers;
* make finding the definitions trivial (`swap` is a utility;
`swap_ranges` is an algorithm).

Since we now have modules-enabled CI, it is now redundant to have ad-hoc
tests that check arbitrary things about our modules support. Instead,
the whole test suite should pass with modules enabled, period.
This patch also removes the module cache path workaround: one would
expect that modules work properly without that workaround. If that
isn't the case and we do run into flaky test failures, we can re-enable
the workaround temporarily (but that would be very vexing and we should
fix Clang ASAP if that's the case).

* `<type_traits>` depends on `std::forward`, so we replaced it with
`static_cast<T&&>`.
* `swap`'s return type is confusing, so it's been rearranged to improve
readabilitiy.
* indicates whether work has been started or completed
* consolidates content that was split for dependency reasons (iff
everything has been merged)
* makes things a lot more fine-grained
* turns sub-CSVs into lists
* puts links into description section and removes patch column
* adds links to c++draft on occasion
These changes heavily prioritise the the reader of the generated HTML
file, not the source.

C++03 didn't support `explicit` conversion operators;
but Clang's C++03 mode does, as an extension, so we can use it.
This lets us make the conversion explicit in `std::function` (even in '03),
and remove some silly metaprogramming in `std::basic_ios`.
Drive-by improvements to the tests for these operators, in addition
to making sure all these tests also run in `c++03` mode.

`propagate_on_container_move_assignment` for `noexcept` specification.
This patch changes it to use `propagate_on_container_swap`, as it should.
