Reimplement the structural-equality checks used to determine whether
two types in different AST contexts are equivalent. Rather than
transforming the type from one context into the other context, we
perform a deep structural comparison of the types. This change
addresses a serious problem with recursive data types like
struct ListNode {
int value;
struct ListNode *Next;
} xList;
