We should mark parent as t.Node | void so such errors can be caught by type checkers. Can you update the function typings?

I have a use case where I want to generate code for a FunctionTypeAnnotation node, and the node has no parent. When the node is passed into the FunctionTypeAnnotation handler, it assumes a parent exists.
I've added a check for the parent so that we don't try to read
.typeoff of an undefined parent.
