    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.
