I don't think x86_64 can use i386-nat.c's implementation, unless
i386-nat.c is extended to handle debug registers that can watch regions
wider than 4 bytes. One thing that definitely needs to be changed is the
size_try_array array, and some of the functions don't expect to see a
region more than 4 bytes long.
But even if x86_64 does not use i386-nat.c, they could roll a similar
implementation, and thus support the same features. FWIW, NEWS
already promises that all x86 targets support those features ;-)
