[IndVarSimplify] Handle the case where both operands are the same when widening IV (#135207)
`WidenIV::widenWithVariantUse` assumes that exactly one of the binop
operands is the IV to be widened. This miscompilation happens when it
tries to sign-extend the "NonIV" operand while the IV is zero-extended.
Closes https://github.com/llvm/llvm-project/issues/135182.
