[PATCH]: Fix mips breakage after fdl-pool patch

Hello Richard,

I broke mips backend with my last scheduler patch that changed interface 
to scheduler dependency analyzer (sched-deps.c).

This obvious patch fixes things by changing mips backend to use new 
interface.

I audited other targets for the same error and they appear to be fine.

Ok for trunk?


Thanks,

Maxim

	* config/mips/mips.c (vr4130_swap_insns_p): Use new interface to
	scheduler dependencies.
