    opts: fix --help=common with '\t' description
    
    Fixes -flto-compression option:
    
    -  -flto-compression-level=<number>     Use z Use zlib/zstd compression level <number> for IL.
    +  -flto-compression-level=<0,19> Use zlib/zstd compression level <number> for IL.
    
    gcc/ChangeLog:
    
            * common.opt: Update -flto-compression-level documentation.
            * opts.cc (print_filtered_help): Do not append range to an
              option that uses \t syntax.
