Marcelina Kościelnicka b98376884e test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. 
These parts keep rereading a Verilog module, then using chparam
to test it with various parameter combinations.  Since the default
parameters are on the large side, this spends a lot of time
needlessly elaborating the default parametrization that will then
be discarded.  Fix it with -deref and manual hierarchy call.

Shaves 30s off the test time on my machine.

Marcelina Kościelnicka cf60699884 synth_ice40: Use opt_dff. 
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

whitequark 081d9318bc ecp5: add support for both 1364.1 and LSE RAM/ROM attributes. 
This commit tries to carefully follow the documented behavior of LSE
and Synplify. It will use `syn_ramstyle` attribute if there are any
write ports, and `syn_romstyle` attribute otherwise.
  * LSE supports both `syn_ramstyle` and `syn_romstyle`.
  * Synplify only supports `syn_ramstyle`, with same values as LSE.
  * Synplify also supports `syn_rw_conflict_logic`, which is not
    documented as supported for LSE.

Limitations of the Yosys implementation:
  * LSE/Synplify support `syn_ramstyle="block_ram,no_rw_check"`
    syntax to turn off insertion of transparency logic. There is
    currently no way to support multiple valued attributes in
    memory_bram. It is also not clear if that is a good idea, since
    it can cause sim/synth mismatches.
  * LSE/Synplify/1364.1 support block ROM inference from full case
    statements. Yosys does not currently perform this transformation.
  * LSE/Synplify propagate `syn_ramstyle`/`syn_romstyle` attributes
    from the module to the inner memories. There is currently no way
    to do this in Yosys (attrmvcp only works on cells and wires).

    can only change case of attribute names).

whitequark 29d130dee9 ice40: remove impossible test. 
iCE40 does not have LUTRAM. This was erroneously added in commit
caab66111e, and tested for BRAM,
essentially a duplicate of the "dpram.ys" test.
