[PATCH 1/7] docs: Create Indices appendix

["Arsen Arsenović" <arsen@aarsen.me>]

gcc/ChangeLog:

	* doc/gcc.texi: Add the Indices appendix, to make texinfo
	generate nice indices overview page.
	(@copying): Move "This file documents the use of the GNU
	compilers" into @copying.  Add quotations around copying.
