    d: Fix build on aarch64-suse-linux
    
    The variables being used to get the result out of TYPE_VECTOR_SUBPARTS
    were being flagged by -Werror=maybe-uninitialized.  As they have already
    been checked for being constant earlier, use `to_constant' instead.
    
    gcc/d/ChangeLog:
    
            * intrinsics.cc (build_shuffle_mask_type): Use to_constant when
            getting the number of subparts from a vector type.
            (expand_intrinsic_vec_shufflevector): Likewise.
