Hello,

For most architectures.  The relationship:

	REGISTER_VIRTUAL_SIZE(N)
	== REGISTER_RAW_SIZE(N)
	== TYPE_LENGTH(REGISTER_VIRTUAL_TYPE(N)

(the exception is the @$(*&@(^$*&^!@ MIPS ...).  Given this, the 
attached patch changes the architecture vector so that it defaults both 
to the register's type size.

I think this is the logical conclusion to MichaelS's earlier patch that 
provided defaults to each.

Thoughts?  I'll look to commit it in a week.
