aarch64: Use type-qualified builtins for XTN[2] Neon intrinsics

Browse Source 
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.
