I at last reached at a state with some spare time and incorporated your
suggestion.  Very sorry for such a late response!

At first I thought it is an easy job of adding similar code around a
bunch of
  (TeX-add-style-hook ... ... LaTeX-dialect)
lines in latex.el, but it turned out that the expected code doesn't
work.  After some survey, I realized that these all lines are not
effective for some years due to the common reason with bug#25563:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25563
I.e., the class options are no longer treated as styles in the sense of
AUCTeX.

I added some codes to recover the functionality of these lines, so they
just began to work again in the codes in the latest git repository.

I added these functionality as well.  The option "dvipdfmx" for these
packages now sets `TeX-PDF-from-DVI' to "Dvipdfmx".

Thanks for your useful suggestion.
