gcc_update (gcc/config/arm/arm-tables.opt): Also depend on gcc/config/arm/arm-fpus.def.

contrib:
	* gcc_update (gcc/config/arm/arm-tables.opt): Also depend on
	gcc/config/arm/arm-fpus.def.

gcc:
	* config/arm/arm-fpus.def: New.
	* config/arm/genopt.sh: Generate Enum and EnumValue entries from
	arm-fpus.def.
	* config/arm/arm-tables.opt: Regenerate.
	* config/arm/arm.c (all_fpus): Move contents to arm-fpus.def.
	(arm_option_override): Don't decode FPU name to string here.
	* config/arm/arm.opt (mfpu=): Use Enum.
	* config/arm/t-arm ($(srcdir)/config/arm/arm-tables.opt, arm.o):
	Update dependencies.
