    aarch64: arm_neon.h - Fix -Wincompatible-pointer-types errors
    
    In the Linux kernel, u64/s64 are [un]signed long long, not [un]signed
    long.  This means that when the `arm_neon.h' header is used by the
    kernel, any use of the `uint64_t' / `in64_t' types needs to be
    correctly cast to the correct `__builtin_aarch64_simd_di' /
    `__builtin_aarch64_simd_df' types when calling the relevant ACLE
    builtins.
    
    This patch adds the necessary fixes to ensure that `vstl1_*' and
    `vldap1_*' intrinsics are correctly defined for use by the kernel.
    
    gcc/ChangeLog:
    
            * config/aarch64/arm_neon.h (vldap1_lane_u64): Add
            `const' to `__builtin_aarch64_simd_di *' cast.
            (vldap1q_lane_u64): Likewise.
            (vldap1_lane_s64): Cast __src to `const __builtin_aarch64_simd_di *'.
            (vldap1q_lane_s64): Likewise.
            (vldap1_lane_f64): Cast __src to `const __builtin_aarch64_simd_df *'.
            (vldap1q_lane_f64): Cast __src to `const __builtin_aarch64_simd_df *'.
            (vldap1_lane_p64): Add `const' to `__builtin_aarch64_simd_di *' cast.
            (vldap1q_lane_p64): Add `const' to `__builtin_aarch64_simd_di *' cast.
            (vstl1_lane_u64): remove stray `const'.
            (vstl1_lane_s64): Cast __src to `__builtin_aarch64_simd_di *'.
            (vstl1q_lane_s64): Likewise.
            (vstl1_lane_f64): Cast __src to `const __builtin_aarch64_simd_df *'.
            (vstl1q_lane_f64): Likewise.
