Subject: [PATCH v3 0/3] overflow.h: Add arithmetic shift helper

This adds the shift overflow helper, selftests, and first usage.

-Kees

v3:
- add even more test cases (type mismatches, more signed overflows).
- fix documentation typo on argument name.
v2:
- swap out selftests with framework from Rasmus, add lots more tests.
- drop double-assignment in helper.
