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.
