Paul Berry f3b2d770ad Migration: rework assignment handling. ...

This change separates the handling of upcast assignments (which we
handle precisely) from downcast assignments (which we handle on a
"best effort" basis).

Should address ~2 exceptions whose stack trace includes the line

_AssignmentChecker._checkAssignment_recursion (package:nnbd_migration/src/edge_builder.dart:2087:9)
