Chris Tate 8d2b3bb2e0 No-arm unit comparisons answer constants instead of trapping ...

- lowerUnitComparison folds ===/!== against a union lacking the unit arm to the constant answer, both operand orders
- a non-droppable operand still evaluates exactly once, riding a throwaway tag test
- union-switch case null / case undefined take the unit-comparison lowering, so a lacking arm never matches
- the unionEq fallback had coerced the literal through the stranded-arm trap, throwing where Node answers false
- corpus 2490-2494: the find-miss repro, every strict and loose spelling, switch unit cases, effect preservation
