doc, xtensa: Clean up Xtensa options documentation [PR122243]

gcc/ChangeLog
	PR other/122243
	* config/xtensa/uclinux.opt (elf2flt, elf2flt=): Mark as Undocumented.
	* config/xtensa/xtensa.opt (mlra): Likewise.
	* doc/invoke.texi (Option Summary) <Xtensa Options>: Remove
	redundant negative forms plus obsolete -mfused-madd option.
	(Xtensa Options): Likewise undocument -mfused-madd.  List
	negative form of -mforce-no-pic.

-Enable or disable use of fused multiply/add and multiply/subtract

-precision than specified by the IEEE standard.  Disabling fused multiply
-add/subtract instructions also ensures that the program output is not
-sensitive to the compiler's ability to combine multiply and add/subtract
