[patch/rfc] Don't include vector registers in ``info registers''

[Andrew Cagney <ac131313@ges.redhat.com>]

Hello,

The attached patch modifies the generic ``info registsters'' command so 
that it precludes vector registers (in addition to floating-point 
registers).  The online doco indicates:

(gdb) help info registers
List of integer registers and their contents, for selected stack frame.
Register name as argument means describe only that register.
(gdb) help info all-registers
List of all registers and their contents, for selected stack frame.
Register name as argument means describe only that register.

I think the change makes the behavour a better match for both the 
documentation and what I think is the intent of the command.  Print a 
minimal set of registers.

It will eventually affect the i386 -- I've a patch to change the type of 
xmm [and mmx] registers to true vectors.  When that is in, ``info 
registers'' will stop displaying the xmm registers.

Thoughts?

enjoy,
Andrew
