aarch64: Use type-qualified builtins for [R]SUBHN[2] Neon intrinsics
Declare unsigned type-qualified builtins and use them to implement (rounding) halving-narrowing-subtract Neon intrinsics. This removes the need for many casts in arm_neon.h. gcc/ChangeLog: 2021-11-09 Jonathan Wright <jonathan.wright@arm.com> * config/aarch64/aarch64-simd-builtins.def: Declare unsigned builtins for [r]subhn[2]. * config/aarch64/arm_neon.h (vsubhn_s16): Remove unnecessary cast. (vsubhn_s32): Likewise. (vsubhn_s64): Likewise. (vsubhn_u16): Use type-qualified builtin and remove casts. (vsubhn_u32): Likewise. (vsubhn_u64): Likewise. (vrsubhn_s16): Remove unnecessary cast.
