* The generate_<tag> function is called twice
* The first time is during the normal TCG generation
* ctx->pre_commit is true
* In the masked cases, we save the mask to the qtmp temporary
* Otherwise, there is nothing to do
* The second call is at the end of gen_commit_packet
* ctx->pre_commit is false
* Generate the call to the helper
