Fix free of NULL value in function ecma_typedarray_helper_dispatch_co…
…nstruct Currently, ecma_op_get_prototype_from_constructor may return NULL and the function didn't raise that exception. Also optimize multiple assignment of prototype_obj_p and multiple access of JERRY_CONTEXT (current_new_target) out. This fixes jerryscript-project#4463 JerryScript-DCO-1.0-Signed-off-by: Yonggang Luo luoyonggang@gmail.com
