    aarch64: Fix ACLE macro __ARM_FEATURE_SVE_VECTOR_OPERATORS
    
    This patch enables ACLE macro __ARM_FEATURE_SVE_VECTOR_OPERATORS to indicate
    that C/C++ language operations are available natively on SVE ACLE types.
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Define
            __ARM_FEATURE_SVE_VECTOR_OPERATORS.
