Converts to SVBool are already considered as a nop, if they are converting an operand from a ptrue or a cmp, because they zero the extra predicate lanes by construction. This patch adds 2 similar cases: - The wide cmp, which were not directly recognized by the test for other forms of cmp - Splats of 1, which will be generated as ptrue, and as such will also zero the extra predicate lines.
