[PATCH] Fix MIPS bootstrap after new enum comparison warning

[Adam Nemet]

Along the lines of the s390 fix:

  http://gcc.gnu.org/ml/gcc-patches/2009-04/msg01343.html

OK if bootstrapping completes on mips64octeon-linux?  (It's already in stage
3.)

	* config/mips/mips.h (mips_tune_attr): New macro.
	* config/mips/mips.md (cpu): Use it.
