feat(minifier): drop var r = [...arguments] if r is not used

[sapphi-red]

Avoid generating var r = [...arguments] if r is not used to reduce the number of iterations.
This would also remove [...arguments].slice(), which would not be removed currently because we don't treat Array::slice as sideeffect free.
