Typeset Big-O complexities with TeX-style notation in libraries/base
In the code review of #15003 (closed), @hvr proposed to typeset Big-Os in TeX-style instead of using italic (1). This will lead to a more idiomatic typesetting.
See 2 for an example.
- *Task:** Replace all italic Big-Os in libraries/base with TeX-style notation.
