[PATCH] aarch64: Add ACLE macro __ARM_FEATURE_SVE_PREDICATE_OPERATORS

[Tejas Belagod]

This patch enables ACLE macro __ARM_FEATURE_SVE_PREDICATE_OPERATORS to indicate
that C/C++ language operations are available natively on SVE ACLE type svbool_t.

gcc/

        * config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Define
        __ARM_FEATURE_SVE_PREDICATE_OPERATORS.

gcc/testsuite

        * gcc.target/aarch64/sve/acle/general/attributes_1.c: Update test for
        __ARM_FEATURE_SVE_PREDICATE_OPERATORS.
        * gcc.target/aarch64/sve/acle/general/attributes_9.c: New.
