ART-tests: Remove DX dependency from 565-checker-rotate
D8 optimizes away the boolean-to-0/1 conversion. This CL moves 2 test
cases to smali where the checks depend on this (and enables D8).
Test: art/test.py -r -b --host -t 565-checker-rotate
Bug: 65168732
Change-Id: If6356dcdab51f6ea27e5cfc6fad1f1c90dbf0de5
