  1. irinterp: set IR_FLAG_REFINED for narrowed PhiNodes 

    `adce_pass!` can transform a `Union`-type `PhiNode` into a narrower
`PhiNode`, but in such cases, the `IR_FLAG_REFINED` flag isn’t set on
that `PhiNode` statement. By setting this flag, irinterp can perform
statement reprocessing using the narrowed `PhiNode`, enabling type
stability in cases like #56387.

- fixes #56387
