	* optabs.h (OTI_eq, OTI_ne, OTI_gt, OTI_ge, OTI_lt, OTI_le)
	(OTI_unord, eq_optab, ne_optab, gt_optab, ge_optab, lt_optab)
	(le_optab, unord_optab): New.

	* optabs.c (prepare_float_lib_cmp): Rewrite.  Get the libfuncs
	from the code_to_optab table, not a giant switch; use
	swap_condition; do widening only if a comparison function that
	we can call exists in a wider mode, not if a cmp_optab insn or
	libfunc exists in a wider mode; call protect_from_queue
	exactly once on each operand.
	(init_optabs): Initialize the new optabs, not the deleted libfuncs.

	* config/gofast.h, config/ia64/ia64.c, config/mips/mips.c
	* config/pa/pa.c, config/rs6000/rs6000.c, config/sparc/sparc.c:
	Set floating point comparison libfuncs using set_optab_libfunc
	on the appropriate optab.

	* config/ia64/ia64.c (ia64_hpux_init_libfuncs): Fix typo.
	* config/rs6000/rs6000.c (rs6000_init_libfuncs): Correct ABI
	selector conditionals.
