movstrti use or loose

The pattern "movstrti" is mentioned in *one* place in expr.c (at MOVE_RATIO
in expr.c; c:a line 234), but not defined in any any port in the distribution,
and not explicitly supported by other code, as the explicit
"HAVE_movstr.."-tests in expr.c (but may be use implicitly via movstr_optab).
So I think support for movstrti as for movstrdi should be added, or movstrti
not be mentioned at all, but I think it's better to include it than exclude it.
Sent to gcc2 as well.
