Subject: Add IRIX options from specs to new mips/iris6.opt

In preparation for the driver only accepting options listed in .opt
files, and not other options that simply happen to match some spec,
this patch adds options from specs in mips/iris6.h to a new
iris6.opt.  (As noted in
<http://gcc.gnu.org/ml/gcc-patches/2011-01/msg00902.html>, I don't
actually know if all these options are IRIX linker options, but they
don't make much sense here if they aren't.)

Tested building cc1 and xgcc for cross to mips-sgi-irix6.5.  OK to
commit?

	* config/mips/iris6.opt: New.
	* config.gcc (mips-sgi-irix6.5*): Use mips/iris6.opt.
