aarch64: Add attributes to the data intrinsics.
All of the data intrinsics don't read/write memory nor they are fp related.
So adding the attributes will improve the code generation slightly.
Built and tested for aarch64-linux-gnu
gcc/ChangeLog:
* config/aarch64/aarch64-builtins.cc (aarch64_init_data_intrinsics): Call
aarch64_get_attributes and update calls to aarch64_general_add_builtin.
