Louis Dionne fd66b44ec1 [libc++] Add an assertion in the subrange constructors with a size hint
Those constructors are very easy to misuse -- one could easily think that
the size passed to the constructor is the size of the range to exhibit
from the subrange. Instead, it's a size hint and it's UB to get it wrong.
Hence, when it's cheap to compute the real size of the range, it's cheap
to make sure that the user didn't get it wrong.

Arthur O'Dwyer 0fb189952c [libc++] Implement structured binding for std::ranges::subrange.
The `get` half of this machinery was already implemented, but the `tuple_size`
and `tuple_element` parts were hiding in [ranges.syn] and therefore missed.

Louis Dionne d153e7d0a5 [libc++] Add a bunch of missing _LIBCPP_HIDE_FROM_ABI in <ranges>
We've been forgetting to add those to most of the <ranges> review.
To avoid forgetting in the future, I added an item in the pre-commit
checklist.

Arthur O'Dwyer e5fbe9f315 [libc++] graph_header_deps.py: Detect files that include themselves.
This wasn't happening before, which led to one slipping in.

Christopher Di Bella a22c55c69b [libcxx][iwyu] 🎨 adds more headers to IWYU
A few slipped through the cracks because D104175 and D104170 didn't
concern themselves with newer commits.
