[rfc] New command ``info vector''

Hello,

(following up a gdb-patches@ thread)

I'd like to propose a new command:

	info vector

This command would display information about an architecture's vector 
unit.  Each architecture could customize it but, by default, it would 
display any vector registers.

On the i386, for instance, it would display the xmm and mmx registers.

I've attached draft documentation.

thoughts?
Andrew
