Make test 656-checker-simd-opt pass on RI.

Move the smali code to Java. Use inlining to expose the
optimization opportunity to ART while hiding it from D8.
Also extend the tests to x86-64.

Test: testrunner.py --host --optimizing --jvm -t 656-checker-simd-opt
Test: testrunner.py --target --optimizing -t 656-checker-simd-opt
