Clean up signed/unsigned in vectorizer.
Rationale:
Currently we have some remaining ugliness around signed and unsigned
SIMD operations due to lack of kUint32 and kUint64 in the HIR. By
"softly" introducing these types, ABS/MIN/MAX/HALVING_ADD/SAD_ACCUMULATE
operations can solely rely on the packed data types to distinguish
between signed and unsigned operations. Cleaner, and also allows for
some code removal in the current loop optimizer.
