cocos2dx舊版本支持arm64修改

修改的版本是cocos2dx.2.2

1.在neon_matrix_impl.c中修改

#if defined(__ARM_NEON__)
為 #if defined(_ARM_ARCH_7)


2.在mat4.c中修改

#if defined(__ARM_NEON__)
為 #if defined(_ARM_ARCH_7)

3. "__curl_rule_01__ "  下載 libcurl for iOS 7.36.0
找到cocos2dx/platform/third_party/ios/
替換 curl/libraries/libcurl.a
替換curl文件夾下的所有.h文件

4."Cast from pointer to smaller type 'int' loses information"
(int)轉變為(long)   注:此方法稍微有點暴力,轉換后有類型警告,不過不影響程序運行 

5.把cocos2dx 3.0中的libwebp.a 替換 cocos2dx/platform/third_party/ios/libraries/libwebp.a
