commit r12-5167-g3e35924cf19b7e45b7fa6f294b8122ba12a8725c

aarch64: Use type-qualified builtins for U[R]HADD Neon intrinsics
Declare unsigned type-qualified builtins and use them to implement
(rounding) halving-add 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: Use BINOPU type
qualifiers in generator macros for u[r]hadd builtins.
* config/aarch64/arm_neon.h (vhadd_s8): Remove unnecessary
cast.
(vhadd_s16): Likewise.
(vhadd_s32): Likewise.
(vhadd_u8): Use type-qualified builtin and remove casts.
(vhadd_u16): Likewise.
(vhadd_u32): Likewise.
(vhaddq_s8): Remove unnecessary cast.
(vhaddq_s16): Likewise.
(vhaddq_s32): Likewise.
(vhaddq_u8): Use type-qualified builtin and remove casts.
(vhaddq_u16): Likewise.
