* config/i386/i386-opts.h: New.

	* gcc/config/i386/i386.c (stringop_alg, ix86_cmodel,
	ix86_asm_dialect, ix86_regparm, ix86_abi, ix86_branch_cost,
	ix86_section_threshold): Remove.
	(ix86_handle_option): Move MAX_CODE_ALIGN define here.  Handle
	OPT_malign_loops_, OPT_malign_jumps_, OPT_malign_functions_ and
	OPT_mbranch_cost_.
	(ix86_option_override_internal): Don't decode strings for options
	other than -march=, -mtune= and -mfpmath=.  Don't allow for
	__attribute__ uses in remaining diagnostics for options with
	string arguments.  Don't check for integer arguments being
	negative.
	* gcc/config/i386/i386.h (enum stringop_alg, enum calling_abi,
	enum tls_dialect, enum cmodel, enum asm_dialect): Move to
	i386-opts.h.
	(ix86_abi, ix86_tls_dialect, ix86_cmodel, ix86_asm_dialect,
	ix86_branch_cost, ix86_section_threshold): Remove.
	* gcc/config/i386/i386.opt (config/i386/i386-opts.h): New
	HeaderInclude.
	(malign-functions=, malign-jumps=, malign-loops=): Use UInteger
	but not Var.
	(masm=): Use Enum and Init.
