    aarch64: Add missing error_mark_node check [PR99381]

    We were missing a check in function_resolver::require_vector_type to see
    if the argument type was already invalid. This was causing us to attempt
    to emit a diagnostic and subsequently ICE in print_type. Fixed thusly.

    gcc/ChangeLog:

            PR target/99381
            * config/aarch64/aarch64-sve-builtins.cc
            (function_resolver::require_vector_type): Handle error_mark_node.
