Arthur O'Dwyer 67151d029b [libc++] [ranges] Implement P2415R2 owning_view.
"What is a view?"
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2415r2.html
https://github.com/cplusplus/draft/pull/5010/files

This was a late-breaking (Oct 2021) change to C++20.
The only thing missing from this patch is that we're supposed
to bump the feature-test macro from
    #define __cpp_lib_ranges 202106L
to
    #define __cpp_lib_ranges 202110L
but we can't do that because we don't implement all of 202106 Ranges yet.

Konstantin Varlamov 68072a7166 [libc++] P0433R2: test that deduction guides are properly SFINAEd away.
Deduction guides for containers should not participate in overload
resolution when called with certain incorrect types (e.g. when called
with a template argument in place of an `InputIterator` that doesn't
qualify as an input iterator). Similarly, class template argument
deduction should not select `unique_ptr` constructors that take a
a pointer.

The tests try out every possible incorrect parameter (but never more
than one incorrect parameter in the same invocation).

Also add deduction guides to the synopsis for associative and unordered
containers (this was accidentally omitted from [D112510](https://reviews.llvm.org/D112510)).

Arthur O'Dwyer dd15c2723c [libc++] [P1518R2] Better CTAD behavior for containers with allocators.
P1518 does the following in C++23 but we'll just do it in C++17 as well:
- Stop requiring `Alloc` to be an allocator on some container-adaptor deduction guides
- Stop deducing from `Allocator` on some sequence container constructors
- Stop deducing from `Allocator` on some other container constructors (libc++ already did this)

The affected constructors are the "allocator-extended" versions of
constructors where the non-allocator arguments are already sufficient
to deduce the allocator type. For example,

    std::pmr::vector<int> v1;
    std::vector v2(v1, std::pmr::new_delete_resource());
    std::stack s2(v1, std::pmr::new_delete_resource());

isn't true. D100271 introduces a new test adaptor to accommodate this

adaptor is _Cpp17InputIterator_, the current `input_iterator` adaptor
has been prefixed with `cpp17_`.

Simon Tatham 4d60467f99 [libcxx] Fix printf formats in two tests.
rGcc69d211d0d65d7b introduced several uses of `printf` with format
directives `%lu` and `%ld` to format values of type `size_t` and
`ptrdiff_t` respectively.

That doesn't reliably work in all C implementations, because those
types aren't necessarily the same thing as 'long int': sometimes
they're not even the same size, and when they are the same size, they
might be officially defined as int rather than long (for example),
which causes clang to emit a diagnostic for the mismatch.

C has special-purpose printf modifier letters for these two types, so
it's safer to use them. Changed all `%lu` on `size_t` to `%zu`, and
all `%ld` on `ptrdiff_t` to `%td`.
