* config/mips/mips-opts.h: New.

	* config/mips/mips.c (enum mips_r10k_cache_barrier_setting): Move
	to mips-opts.h.
	(mips_abi, mips_code_readable, mips_r10k_cache_barriee): Remove.
	(mips_handle_option): Don't handle OPT_mabi_, OPT_mcode_readable_
	or OPT_mr10k_cache_barrier_ here.  Access mips_cache_flush_func
	via opts pointer.
	* config/mips/mips.h (enum mips_code_readable_setting): Move to
	mips-opts.h.
	(mips_abi, mips_code_readable): Don't declare.
	* config/mips/mips.opt (config/mips/mips-opts.h): New
	HeaderInclude.
	(mabi=): Use Enum and Var.
	(mips_abi): New Enum and EnumValue entries.
	(mcode-readable=): Use Enum and Var.
	(mips_code_readable_setting): New Enum and EnumValue entries.
	(mr10k-cache-barrier=): Use Enum and Var.
	(mips_r10k_cache_barrier_setting): New Enum and EnumValue entries.
