aarch64: Use type-qualified builtins for XTN[2] Neon intrinsics
Declare unsigned type-qualified builtins and use them for XTN[2] Neon
intrinsics. This removes the need for casts in arm_neon.h.
gcc/ChangeLog:
2021-11-08 Jonathan Wright <jonathan.wright@arm.com>
* config/aarch64/aarch64-simd-builtins.def: Declare unsigned
type-qualified builtins for XTN[2].
* config/aarch64/arm_neon.h (vmovn_high_u16): Use type-
qualified builtin and remove casts.
(vmovn_high_u32): Likewise.
(vmovn_high_u64): Likewise.
(vmovn_u16): Likewise.
(vmovn_u32): Likewise.
(vmovn_u64): Likewise.
