Support for narrow operands in "dangerous" operations.
Rationale:
Under strict conditions, even operations that are sensitive
to higher order bits can vectorize by inspecting the operands
carefully. This enables more vectorization, as demonstrated
by the removal of quite a few TODOs.
Test: test-art-target, test-art-host
