    aarch64: Use type-qualified builtins for PMUL[L] Neon intrinsics
    
    Declare poly type-qualified builtins and use them for PMUL[L] 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: Use poly type
            qualifier in builtin generator macros.
            * config/aarch64/arm_neon.h (vmul_p8): Use type-qualified
            builtin and remove casts.
            (vmulq_p8): Likewise.
            (vmull_high_p8): Likewise.
            (vmull_p8): Likewise.
