GrowableArrays do not work with jlong, use uint64_t

GrowableArray's do not work with jlong, and must use uint64_t to get the same capabilities.

jvmtiTagMap.cpp:857
 GrowableArray<jlong>* _tag_results; // collected tags

Must be changed to
 GrowableArray<uint64_t>* _tag_results;

Along with any other references to jlong.
