(attributes): Rearrange order, so that condition clobbering

(attributes): Rearrange order, so that condition clobbering
	can be automatically determined for call insns.
	(attribute cpu): Add new cpu ARM7.
	(attribute type): Add new type MULT.
	(attribute prog_mode): New attribute.
	(attribute conds): Clobbering of call insns can now be determined
	using prog_mode attribute.
	(function units "write_buf", "write_blockage"): Model the write buffer
	as two function units, so that conflicts are avoided more often.
	(funcion unit "core"): New function unit, so that elapsed cycles can
	be more accurately determined.
	(all anonymous patterns): Add names.
	(mulsidi3, umulsidi3): New patterns available with fast multiply
	variants.
	(all call insns): The conds attribute is now determined automatically.
	(zero_extendhisi): Expand for architecture 4 variants if appropriate.
	(*zero_extendhisi_insn): New pattern.
	(extendqi{hi,si}, extendhisi): Expand for architecture 4 variants if
	appropriate.
	(*extendhisi_insn, *extendqihi, *extendqisi): New patterns.
	(storehi_single_op): New expand.
	(movhi): Handle architecture 4 expansion.
	(*movhi_insn_arch4): New pattern.
	(*movhi_*): Adjust applicability conditions to handle architecture 4.
	(reload_outdf): Handle pre/post inc/dec reloads.
	(tablejump): Delete.
	(matcher for optimized tablejump): delete.
	(casesi): New expand.
	(casesi_internal): New pattern.
	(*movsi_insn): Much simpified now that constants are handled
	properly.
	(movaddr): New expand.
	(movsf, movdf): No need to force constants into the pool any more.
	(*movdf_hard_insn): Much simplified.
	(consttable_4, consttable_8, consttable_end, align_4): New patterns
	for supporting embedded constants.
