mips.h (CUMULATIVE_ARGS): Rename fp_regs to num_fprs to avoid clash with Irix header file sys/ucontext.h.

	* config/mips/mips.h (CUMULATIVE_ARGS): Rename fp_regs to num_fprs
	to avoid clash with Irix header file sys/ucontext.h.  Rename gp_regs
	to num_gprs for symmetry.
	* config/mips/mips.c: Adjust accordingly.
