some arches didnt call sim_args_command(), now they do.  bug fix for them.

some arches would display an error message when users passed an old command 
option and inform them of the new one.  i think people have had long enough 
for that migration, and they can pretty easily figure things out with the 
normal help output.

m68hc11 provided a dedicated "info" to call an arch-specific sim_get_info(), 
but the common sim_info() entry point also calls that.  m68hc11 would also 
rewrite its internal device tree when people changed files, but this behavior 
deviates from the standard sim behavior, so i dont think it should be there at 
all.  the normal sim workflow (target;file;load) should continue to work.

m32r provided a dedicated hook for reading two pseudo registers, but that 
should be done via the normal gdb interface rather than hooking the command 
line like this.

i think that sums up all deviations.
