Correct. The two main cases we need to cover are the following.
I'll make a comment to explain the logic.
```
struct Test
{
Test& operator=(const Test&) = delete;
int x;
};
```
In this case `DefaultedCopyAssignmentIsDeleted` is `false` on the
`CXXRecordDecl`. So we need to query `isDeleted` on the copy assignment
operator `CXXMethodDecl`.
```
struct Test
{
int& x;
};
```
In this case we have no `CXXMethodDecl` for the copy assignment operator so we
need to check if `DefaultedCopyAssignmentIsDeleted` is `true` on the
`CXXRecordDecl`.
