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.
