[PATCH] gas: improve --gsframe documentation

[Sam James]

I omitted documentation in 8aad677a12832885acd5be1de8f41e740b8e713d in
error. Rectify that with:
1) changing ---help to mention bare `--gsframe` too, as we're not
   getting rid of that;

2) dropping the 'default: no' text, as it's not useful as-is now we have
   `--gsframe` explicitly documented again. It can be restored as-needed
   later once we have a configure flag for determining the default;

3) adding the new --gsframe=[no|yes] form to as.texi.

	* gas/as.c: Tweak --gsframe= help text.
	* gas/doc/as.texi: Document --gsframe=[no|yes].

Jan, does this look better? Notably, I've dropped the 'default: ...' text,
as I think it's noise for now. I should've really clocked that its inclusion
was really hinting that --gsframe itself should remain listed.
