[PATCH] sim: add __attribute__((unused)) to <arch>_fill_argbuf_tp function

[Simon Marchi <simon.marchi@efficios.com>]

I get this when building with --enable-targets=all:

      CC       m32r/mloopx.o
    m32r/mloopx.c:37:1: error: ‘m32rxf_fill_argbuf_tp’ defined but not used [-Werror=unused-function]
       37 | m32rxf_fill_argbuf_tp (const SIM_CPU *cpu, ARGBUF *abuf,
          | ^~~~~~~~~~~~~~~~~~~~~

      CC       m32r/mloop2.o
    m32r/mloop2.c:37:1: error: ‘m32r2f_fill_argbuf_tp’ defined but not used [-Werror=unused-function]
       37 | m32r2f_fill_argbuf_tp (const SIM_CPU *cpu, ARGBUF *abuf,
          | ^~~~~~~~~~~~~~~~~~~~~

I don't know this code, so I didn't do an in-depth analysis of the
situation.  Adding the __attribute__((unused)) makes the warning go away
(this is what this patch does), but perhaps there's a better way or the
warning is the sign that something is wrong.
