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.
> 
> Bug: v8:7703
