doc, or1k: Clean up OpenRISC option documentation [PR122243]

I'm not sure what the rationale is for having "RejectNegative" on all
of the options that control instruction usage except for -mdouble-float,
but with this patch the documentation matches what is in the .opt files.

gcc/ChangeLog
	PR other/122243
	* config/or1k/elf.opt (mnewlib): Mark obsolete option as
	"Undocumented".
	* config/or1k/or1k.opt (mcmov): Don't use future tense in doc string.
	(msfimm): Likewise.
	(mshftimm): Likewise.
	* doc/invoke.texi (Option Summary) <OpenRISC Options>: Don't
	document -mnewlib.
	(OpenRISC Options): Likewise.  Add @opindex entry for
	-mno-double-float.  Fix more instances of incorrect use of future
	tense.
