Whoops, attached wrong patch to last message. This is the right patch.
Trivial fallout from the recent combine work. We end up with a srai
rather than an xor in some of the saturation sequences. Both variants
look equally performant, so I'm just adjusting the expected test output.
Pushing to the trunk.

[RISC-V] Fix more fallout from combine.c changes
Trivial fallout from the recent combine work. We end up with a srai rather
than an xor in some of the saturation sequences. Both variants look equally
performant, so I'm just adjusting the expected test output.
