[PATCH v2 1/8] aarch64: Fix ACLE macro __ARM_FEATURE_SVE_VECTOR_OPERATORS

[Tejas Belagod]

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.
