i965/fs: Explicitly disallow CSE on predicated instructions.
The existing inst->is_partial_write() already disallows predicated instructions, so this has no functional change. However, it's worth doing explicitly since the CSE pass does not consider the flag register. This means it could blindly factor out operations that use the same sources, but which have different condition codes set. This prevents a regression in the next commit.
