	* aarch64-simd.md
	(aarch64_<ANY_EXTEND:su><ADDSUB:optab>l2<mode>_internal): Rename to ...
	(aarch64_<ANY_EXTEND:su><ADDSUB:optab>l<mode>_hi_internal): ... this;
	Insert '\t' to output template.
	(aarch64_<ANY_EXTEND:su><ADDSUB:optab>l<mode>_lo_internal): New.
	(aarch64_saddl2<mode>, aarch64_uaddl2<mode>): Modify to call
	gen_aarch64_<ANY_EXTEND:su><ADDSUB:optab>l<mode>_hi_internal() instead.
	(aarch64_ssubl2<mode>, aarch64_usubl2<mode>): Ditto.
