    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.

    gcc/ChangeLog:

            PR target/110100
            * config/aarch64/aarch64-builtins.cc (aarch64_expand_builtin_ls64):
            Use input operand for the destination address.
            * config/aarch64/aarch64.md (st64b): Fix constraint on address
            operand.
