[REDO] Parallel: More precise boundary in ObjectStartArray::object_starts_in_range

        The fix in JDK-8279699 uses `align_up` for `end_addr`, which leads to unreserved space if the result, after align_up, is reserve_end.
        (The original code on master should suffer from the same problem as well if the passed-in arg `end_addr` is `reserve_end`.)

        One way to workaround the problem could be:

        ```
          if (start_addr == end_addr) {
            // empty
            return false;
          }
          ...
          jbyte* end_block = block_for_addr(end_addr - 1);

          for (jbyte* block = start_block; block <= end_block; block++) {
        ```
