Otherwise ok.
See modified patch below. If you think vrp98.c is unnecessary, feel free
to dump it :).
If ok, could you commit it for me please? I don't have commit access.

* gcc.dg/tree-ssa/vrp98.c: New testcase.
* gcc.target/avr/uint8-single-reg.c: New testcase.
I went ahead and committed this as-is.
I do think the vrp98 testcase is useful as it verifies that VRP is doing
what we want in a target independent way. It's a good complement to the
AVR specific testcase.
Thanks,
Jeff
