Actually emit an availability diagnostic for a reference to an unavailable decl.
| Ctx | The context that the reference occurred in |
| ReferringDecl | The exact declaration that was referenced. |
| OffendingDecl | A related decl to ReferringDecl that has an availability attribute corresponding to K attached to it. Note that this may not be the same as ReferringDecl, i.e. if an EnumDecl is annotated and we refer to a member EnumConstantDecl, ReferringDecl is the EnumConstantDecl and OffendingDecl is the EnumDecl. |

For example, we should emit an unavailable diagnostic in a deprecated context, but not the other way around.

The diagnostic we should emit for D, and the declaration that originated it, or AR_Available.
| D | The declaration to check. |
| Message | If non-null, this will be populated with the message from the availability attribute that is selected. |
| ClassReceiver | If we're checking the method of a class message send, the class. Otherwise nullptr. |
