[patch] h8300.c: Clean up code.

[Kazu Hirata <kazu at isuzu dot hxi dot com>]

Hi,

Attached is a patch to rearrange code in config/h8300/h8300.c.

Here is a description on each change.

1) There is a comment typo, where "H8/300" shuold be "H8/300H".

2) The new functions, round_frame_size, compute_saved_regs, push, and
   pop, remove redundancy found in function_prologue and
   function_epilogue.

3) push_order and pop_order are removed as their contents are deeply
   embedded in the code already.  As an alternative, I modified some
   comments.

The reason for this patch is that it makes it easy for me to convert
FUNCTION_EPILOGUE to "epilogue" in RTL for efficient function returns.
I am testing the RTL version of epilogue in my personal tree.  So far
things are going OK.

OK to apply?

Thanks,

Kazu Hirata
