whitequark e0def9e4d9 memory_map: add -attr option, to respect inference attributes. 
Before this commit, memory_map (which is always a part of a synth
script) would always pick up any $mem cell that was not processed
by a preceding pass and lower it down to $dff/$mux cells.
This is undesirable for two reasons:
  * If there is an explicit inference attribute set on a $mem cell,
    e.g. (* ram_block *), then it is arguably incorrect to map such
    a memory to $dff/$mux cells.
  * If memory_map tries to lower a memory that was intended to
    be mapped to a large BRAM, it often takes extraordinarily long
    time to finish, produces an extremely large log file, and outputs
    an unusable design.

After this commit, properly invoked memory_map will not map any
memory that has an explicit inference attribute specified, solving
the first issue, and alleviating the second. The default behavior
is not changed.

Claire Wolf f72b65b2a5 Using LFSR counter for ezSAT::manyhot() 
The only user of this API right now is the puzzle3d benchmark and
it sees a slight reduction in CNF size from this, but the performance
difference is within the noise of measurement on my system.
