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.
