    aarch64: Fix wrong code with st64b builtin [PR110100]

    The st64b pattern incorrectly had an output constraint on the register
    operand containing the destination address for the store, leading to
    wrong code. This patch fixes that.

            Use input operand for the destination address.
            * config/aarch64/aarch64.md (st64b): Fix constraint on address
            operand.
