new-ra code sizes on Hitachi H8

Well, to be overly precise, on the 300H and H8S series: 8 32-bit 
registers, which can be individually treated as 16 16-bit registers, and 
half of those can be individually treated as 16 8-bit registers.  Beats 
the x86 by a long ways anyway ;-).

Probably not as happy as I am ;-).  I've been using gcc targeting 
Hitatchi H8, H8300H, and H8S micros for years now and its been a 
godsend.  I want to take this opportunity to thank everyone involved in 
the gcc project, and especially those working the Hitachi angles, and 
especially you Kazu, I've seen a lot of activity by you in recent 
months.  Know that your work is directly helping to improve the quality 
of life of people all over the globe.
