[PATCH] D151523: [ASTStructuralEquivalence] Fix crash when ObjCCategoryDecl doesn't have corresponding ObjCInterfaceDecl.

Kinda a follow-up to D121176 <https://reviews.llvm.org/D121176>.

One big alternative that I've considered is to store interface name in `ObjCCategoryDecl` because when we parse `@interface InterfaceName(CategoryName)` we know the interface name. The intention was to allow

  @interface A(X) @end

and

  @interface A @end
  @interface A(X) @end

as equivalent. But I'm not convinced it is the right call and that's why it doesn't justify the extra effort.
