Figure out if Sourcepawn enum structs are going to break API

[rtldg]

alliedmodders/sourcepawn#945 does some things like make enum structs not really arrays anymore.
bhoptimer has API which passes structs around as array parameters like this for reasons:

native void Shavit_SaveSnapshot(int client, any[] snapshot, int size = sizeof(timer_snapshot_t));
native bool Shavit_LoadSnapshot(int client, any[] snapshot, int size = sizeof(timer_snapshot_t), bool force = false);

Check if this is a problem whenever SM 1.12's sourcepawn submodule is updated.
