mips.opt (mdmx, [...]): New options.

* config/mips/mips.opt (mdmx, mmt, mno-mdmx): New options.
	(mips16): Fix typo.
	* config/mips/mips.h (ASM_SPEC): Pass -mmt/-mno-mt and -mdmx/-mno-mdmx
	on to the assembler.  Improve handling of -mno-mips16.  Add handling
	of -mno-mips3d, -mno-dsp, -mno-dspr2.
	* doc/invoke.texi (MIPS Options): Whitespace cleanup.  Fix wrong use
	of @itemx.  Document -mno-dsp, -mno-dspr2, -mno-paired-single, -mdmx,
	-mno-mdmx, -mno-mips3d, -mmt and -mno-mt.
