[patch] multi-arch CANNOT_^&*^*&_REGISTER(); Was: New gdb 31 & 64 bit patches for S/390

[Andrew Cagney <ac131313@cygnus.com>]

Hello,

This multi-arches CANNOT_FETCH_REGISTER() and CANNOT_STORE_REGISTER(). 
It should be equivalent to the original s390 gdbarch.sh patch.
I should note that the original s390 patch included a change that added 
the concept of a default expression/values.  I've left that idea for a 
rain day.

Well it can't be a (ugh) #ifdef :-)
