    gccrs: dump: Remove tokenstream dump
    
    This dump will soon replace ast-pretty print and is hence no longer
    required.
    
    gcc/rust/ChangeLog:
    
            * rust-session-manager.cc (Session::enable_dump): Remove
            tokenstream dump.
            (Session::compile_crate): Likewise.
            (Session::dump_tokenstream): Likewise.
            * rust-session-manager.h (struct CompileOptions): Likewise.
