It's missing the "registration" of the three new classes in std.cc.in.

Follows up on: https://gcc.gnu.org/pipermail/libstdc++/2025-May/061535.html To improve naming conventions, this series includes three new commits: * Two commits to rename _ExtentsStorage::_M_dynamic_extents, and extents::_M_dynamic_extents. * One commit to cleanup whitespace errors in extents. The changes to the existing commits are: * Fix division by zero bug. * Rename subextents -> extents. * Default arguments for __{static,dynamic}_extents. * Default argument for __static_quotient. * Four times: use range-based for. * Eliminate __has_static_zero * Short-circuit in __static_quotient. * Optimize __exts_prod for rank == rank_dynamic. This review suggestion was intentionally skipped: * Inline helper of __exts_prod, because with the additional optimization for rank == rank_dynamic, having two separate functions makes the highlevel structure a little bit more obvious. Additionally, there's numerous changes planned that might make one of the two functions much more verbose.
