gnat_ugn.texi: Remove extra paren check from list of checks for redundant constructs Add...

	* gnat_ugn.texi:
	Remove extra paren check from list of checks for redundant constructs
	Add documentation of new -gnatyx style check (check extra parens)
	Remove paragraph about gnatelim debug options.

	* gnat_rm.texi: Document that Ada.Streams now forbids creating stream
	objects rather than forbidding dependencies on the package Ada.Streams.

	* sinfo.ads: Add ??? note that we should document pragmas passed to
	back end.

	* g-expect.ads: Fix a few typos in the comments.
