[libc++] Remove dedicated namespaces for ranges functions ( #76543 )
...
We originally put implementation-detail function objects into individual
namespaces for `std::ranges` without a good reason for doing so. This
practice was continued, presumably because there was prior art. Since
there's no reason to keep these namespaces, this commit removes them,
which will slightly impact binary size.
This commit does not apply to CPOs, some of which need additional work.

[libc++] Remove _LIBCPP_DISABLE_NODISCARD_EXTENSIONS and refactor the tests ( #87094 )
...
This also adds a few tests that were missing.

[libc++] Optimize ranges::minmax ( #87335 )
...
This allows Clang to vectorize the loop.

[libc++][hardening] Categorize more 'valid-element-access' checks. ( #71620 )

[libc++][hardening][NFC] Introduce _LIBCPP_ASSERT_UNCATEGORIZED.
...
Replace most uses of `_LIBCPP_ASSERT` with
`_LIBCPP_ASSERT_UNCATEGORIZED`.
This is done as a prerequisite to introducing hardened mode to libc++.
The idea is to make enabling assertions an opt-in with (somewhat)
fine-grained controls over which categories of assertions are enabled.
The vast majority of assertions are currently uncategorized; the new
macro will allow turning on `_LIBCPP_ASSERT` (the underlying mechanism
for all kinds of assertions) without enabling all the uncategorized
assertions (in the future; this patch preserves the current behavior).

[libc++][NFC] Apply clang-format on large parts of the code base
...
This commit does a pass of clang-format over files in libc++ that
don't require major changes to conform to our style guide, or for
which we're not overly concerned about conflicting with in-flight
patches or hindering the git blame.
This roughly covers:
- benchmarks
- range algorithms
- concepts
- type traits
I did a manual verification of all the changes, and in particular I
applied clang-format on/off annotations in a few places where the
result was less readable after than before. This was not necessary
in a lot of places, however I did find that clang-format had pretty
bad taste when it comes to formatting concepts.

[libc++][Modules] Add missing includes and exports
...
Several headers are missing includes for things they use.
type_traits.is_enum needs to export type_traits.integral_constant so that clients can access its `value` member without explicitly including __type_traits/integral_constant.h themselves.
Make `subrange_fwd` a peer submodule to `subrange` rather than a submodule of it, and have `subrange` export `subrange_fwd`. That will make it easier to programmatically generate modules for the private detail headers, and it will accomplish the same effect that __ranges/subrange.h will make subrange_kind visible.

[libc++][NFC] Replace _LIBCPP_STD_VER > x with _LIBCPP_STD_VER >= x
...
This change is almost fully mechanical. The only interesting change is in `generate_feature_test_macro_components.py` to generate `_LIBCPP_STD_VER >=` instead. To avoid churn in the git-blame this commit should be added to the `.git-blame-ignore-revs` once committed.
