        Failure addressed by not exposing the new test to the jitless environment.
        (jgruber@ on TBR).
    
        New enum RelocInfo::COMPRESSED_EMBEDDED_OBJECT created to support
        compressed pointers in generated code. Enum name EMBEDDED_OBJECT
        changed to FULL_EMBEDDED_OBJECT.
    
        RelocInfo::[set_]target_object() abstract away the difference between
        FULL_EMBEDDED_OBJECT and COMPRESSED_EMBEDDED_OBJECT.
    
        Compressed embedded objects can only be created at this time on
        x64 with pointer compression turned on. Arm64 constant pools don't
        support compressed objects at this time.
