Hello,

This adds mmx registers to the i386.

Several notes:

It depends on an earlier patch I submitted that eliminates 
register_byte() and register_raw_size() from the i386.

It probably works better if the ``info vector'' command is added.

If someone has a bit of code for testing this, I'm most interested.  I 
think its correct :-)

Assuming I've got it right ..., yes, it is that easy :-)

comments? ok?
Andrew
