Implement Sum-of-Abs-Differences idiom recognition.
Rationale:
Currently just on ARM64 (x86 lacks proper support),
using the SAD idiom yields great speedup on loops
that compute the sum-of-abs-difference operation.
Also includes some refinements around type conversions.
Speedup ExoPlayerAudio (golem run):
1.3x on ARM64
1.1x on x86
Test: test-art-host test-art-target
Bug: 64091002
