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

v4:
- actually fix docs typo
- rename to check_shl_overflow()
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.
