[RFC] frv-tdep.c: Use refine_prologue_limit() instead of skip_prologue_using_sal()

The rs6000 contains this:
   if (lim_pc == 0)
     lim_pc = refine_prologue_limit (pc, lim_pc);
which I believe scores as a ``Not not true'' :-)

More seriously, what's the case you've encountered?

GDB should be using the dwarf2 debug info when setting the prologue 
breakpoint[s], how hard is it to do that?
