IMO, these should simply be added as new registers.  Since the name
$gs is already taken, why not add a $gs_base register?

H.J. Lu has recently converted the i386 target to use target
descriptions; it should be easy to add new registers now.
They could go in 32bit-linux.xml or in some other file that could be
shared among OS's.  H.J. may have some more ideas.
