    waccess: Fix up pass_waccess::check_alloc_size_call [PR102009]

    This function punts if the builtins have no arguments, but as can be se=
en
    on the testcase, even if it has some arguments but alloc_size attribute=
's
    arguments point to arguments that aren't passed, we get a warning earli=
er
    from the FE but should punt rather than ICE on it.
    Other users of alloc_size attribute e.g. in
    tree-object-size.c (alloc_object_size) punt similarly and similarly
    even in the same TU maybe_warn_nonstring_arg correctly verifies calls h=
ave
    enough arguments.
