decodetree: Drop check for less than 2 patterns in a group
While it makes little sense for the end product to have a group
containing only a single pattern, avoiding this case within an
incremental patch set is troublesome.
Because this is expected to be a transient condition, do not
bother "optimizing" this case, e.g. by folding away the group.
