PinyinIME crashed in userdebug version

The root cause of this issue is nativeImOpenDecoder method
is optimized by JAVA compiler in userdebug version. And JVM could
not find this symbol in the virtual table of PinyinDecoderService
class, and this will cause JNI library load fail.
Solution is avoid this optimization.
