    Original change's description:
    > [ptr-compr] New RelocInfo for compressed pointers.
    > 
    > 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.
