Similar as [3/6], these intrinsics were implemented before the instruction
pattern "aarch64_rsqrts<mode>" added, that these intrinsics were implemented
through inline assembly.

This mirgrate the implementation to builtin.

This ChangeLog format is incorrect.

It looks like you're missing vrsqrts_f64, could you please add that?

I haven't found vrsqrts_f64 before this rewrite patch.
