When lowering makes this transformation it should proceed lowering from the original next node of the CndSel, not from op2. If we proceed lowering from op2 we will relower some nodes.

Fix #106876

Don't have a reasonably small test case to add here.

When lowering makes this transformation it should proceed lowering from
the original next node of the `CndSel`, not from `op2`. If we proceed
lowering from `op2` we will relower some nodes.
