Chris Tate 3134642f19 Keep undefined out of the shape overlay's set of constructed functions ...

A union that is a Set element or a Map key is stored as a union box, and
a union type has one representation in a program. The overlay's
`Set<ts.Node | undefined>` made the native compiler box every
`ts.Node | undefined` value, including each optional child a syntax node
returns. The set now holds the defined nodes only.
