      Description

      In LibraryCallKit::inline_vector_shuffle_iota(), the "VectorLoadConstNode" will be created to get an initial index vector for shuffle. Before creating it, the compiler doesn't check whether the current platform supports this opcode. If the compiler created the node while the backend doesn't have the codegen support for it, the jvm will crash with "bad ad file'.
