    Reland "[ptr-compr] New RelocInfo for compressed pointers." · ed319e84
    Mike Stanton authored
    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.
