android5.1, android6.0.1当cpu是64位时，无法hook

调试后发现结构体错了， void *dexCacheResolvedMethods = (void *) readAddr( (void *) ((char *) hookMethod + OFFSET_dex_cache_resolved_methods_in_ArtMethod)); dexCacheResolvedMethods是一个非法地址，memcpy就崩溃了。

64位GcRoot转为指针似乎比较奇怪 http://androidxref.com/6.0.1_r10/xref/art/runtime/mirror/object_reference.h#70

应该要具体结合调试来看怎么从GcRoot获取到实际对象
