These intrinsics were implemented before the instruction pattern
"aarch64_rsqrte<mode>" added, that these intrinsics were implemented through
inline assembly.

This mirgrate the implementation to builtin.

         * config/aarch64/aarch64-builtins.def (rsqrte): New builtins for modes
         * config/aarch64/aarch64-simd.md (aarch64_rsqrte_<mode>2): Rename to
         * config/aarch64/aarch64.c (get_rsqrte_type): Update gen* name.
         * config/aarch64/arm_neon.h (vrsqrts_f32): Remove inline assembly.  Use
         (vrsqrted_f64): Likewise.
         (vrsqrte_f32): Likewise.
         (vrsqrte_f64): Likewise.
         (vrsqrteq_f32): Likewise.
         (vrsqrteq_f64): Likewise.
