[PATCH, MIPS] Add 34Kn cpu

This patch makes GCC know about -march=34kn.  MIPS asked us to add 
support for this processor to our local source base a couple of years 
ago; it's basically a 34Kc without the DSP ASE.  OK for mainline?

I have posted the corresponding assembler patch here:
http://sourceware.org/ml/binutils/2012-08/msg00008.html

	* config/mips/mips-cpus.def (34kn): New.
	* config/mips/mips.h (MIPS_ARCH_FLOAT_SPEC): Add 34kn.
	(BASE_DRIVER_SELF_SPECS): Do not imply -mdsp for the 34kn.

Needs adding to invoke.texi too.  OK with that change, thanks.

And http://gcc.gnu.org/gcc-4.8/changes.html :-)

Eh, this is pretty trivial compared to some of the other MIPS 
improvements that are either recently committed or in the pipeline -- 
specifically, the microMIPS support Catherine is working on, and the 
recently-committed Netlogic XLP patch.  We also have a batch of MIPS16 
improvements that have not been submitted yet, including the missing 
TLS/PIC bits to make MIPS16 work with Linux.  (I can't claim to be 
responsible for any of this good stuff myself, though; I'm just helping 
with whacking at some smaller patches in our backlog while I'm between 
other projects.)

Well, my hope is that you'll document these as well. ;-)  Let me
know if there is anything I can help with.

That's cool!  Happy whacking.
