aarch64: add attributes to the prefetch_builtins

This adds the attributes associated with prefetch to the bultins.
Just call aarch64_get_attributes with FLAG_PREFETCH_MEMORY to get the attributes.

Built and tested for aarch64-linux-gnu.

gcc/ChangeLog:

	* config/aarch64/aarch64-builtins.cc (aarch64_init_prefetch_builtin):
	Updete call to aarch64_general_add_builtin in AARCH64_INIT_PREFETCH_BUILTIN.
	Add new variable prefetch_attrs.
