Marcelina Kościelnicka eb76d35e80 memory_dff: Fix needlessly duplicating enable bits. 
When the register being merged into the EN signal happens to be a $sdff,
the current code creates a new $mux for every bit, even if they happen
to be identical (as is usually the case), preventing proper grouping
further down the flow.  Fix this by adding a simple cache.

Fixes #2409.
