PATCH: Morpho Technologies register patch

[Mark Mitchell <mark@codesourcery.com>]

I noticed that in MI mode, which the Morpho patches previously posted,
I wasn't seeing all of the registers with -data-list-register-names.
The problem was that we had hard-coded the last register number into
mt_register_name; this change updates that to use the enumeral that
actually corresponds to the last register number, rather than just
using the register that happens to be last.

I've now got three patches outstanding:

http://sources.redhat.com/ml/gdb-patches/2006-04/msg00141.html

http://sources.redhat.com/ml/gdb-patches/2006-04/msg00251.html

and this one.

Kevin, I see that you're listed as the maintainer for this port, so
I've CC'd you on this mail, in the hopes that you might have a spare
minute to look at the patches.

Thanks,
