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

Browse source 
Declare unsigned type-qualified builtins and use them for [R]SHRN[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 type-
	qualified builtins for [R]SHRN[2].
	* config/aarch64/arm_neon.h (vshrn_n_u16): Use type-qualified
	builtin and remove casts.
	(vshrn_n_u32): Likewise.
	(vshrn_n_u64): Likewise.
