[LV] Generate scalar xor for VPInstruction::Not if possible. (#152628)
`VPInstruction::Not` which will generate xor instruction is widely used
for the exit condition. This patch make `VPInstruction::Not` generate
scalar `xor` if possible.

This can help reducing the (splat true) in the `xor` and make `xor` be
scalar.
