Don't force a list of identical elements
This makes a big difference when a pair of lists is attempted
to be streamed and the first one is of trivial primitive elements
(e.g., when implementing a fold as a special case of mapAccum with
the output list containing only ()). Forcing the first trivial list
would cause the second non-trivial list to be represented as nested
thunks, burdening GC greatly.
