xilinx: do not make DSP48E1 a whitebox for ABC9 by default (#2325) 
* xilinx: eliminate SCCs from DSP48E1 model

* xilinx: add SCC test for DSP48E1

* Update techlibs/xilinx/cells_sim.v

* xilinx: Gate DSP48E1 being a whitebox behind ALLOW_WHITEBOX_DSP48E1

Have a test that checks it works through ABC9 when enabled

Dan Ravensloft 1a07b330f8 intel_alm: Add multiply signedness to cells 
Quartus assumes unsigned multiplication by default, breaking signed
multiplies, so add an input signedness parameter to the MISTRAL_MUL*
cells to propagate to Quartus' <family>_mac cells.

Marcelina Kościelnicka 50d532f01c techmap/shift_shiftx: Remove the "shiftx2mux" special path. 
Our techmap rules for $shift and $shiftx cells contained a special path
that aimed to decompose the shift LSB-first instead of MSB-first in
select cases that come up in pmux lowering.  This path was needlessly
overcomplicated and contained bugs.

Instead of doing that, just switch over the main path to iterate
LSB-first (except for the specially-handled MSB for signed shifts
and overflow handling).  This also makes the code consistent with
shl/shr/sshl/sshr cells, which are already decomposed LSB-first.

Fixes #2346.

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.

Marcelina Kościelnicka 347dd01c2f xilinx: Fix srl regression. 
Of standard yosys cells, xilinx_srl only works on $_DFF_?_ and
$_DFFE_?P_, which get upgraded to $_SDFFE_?P?P_ by dfflegalize at the
point where xilinx_srl is called for non-abc9.  Fix this by running
ff_map.v first, resulting in FDRE cells, which are handled correctly.

Dan Ravensloft 5b779f7f4e intel_alm: direct LUTRAM cell instantiation 
By instantiating the LUTRAM cell directly, we avoid a trip through
altsyncram, which speeds up Quartus synthesis time. This also gives
a little more flexibility, as Yosys can build RAMs out of individual
32x1 LUTRAM cells.

While working on this, I discovered that the mem_init0 parameter of
<family>_mlab_cell gets ignored by Quartus.

Dan Ravensloft 2e37e62e6b synth_intel_alm: alternative synthesis for Intel FPGAs 
By operating at a layer of abstraction over the rather clumsy Intel primitives,
we can avoid special hacks like `dffinit -highlow` in favour of simple techmapping.

This also makes the primitives much easier to manipulate, and more descriptive
(no more cyclonev_lcell_comb to mean anything from a LUT2 to a LUT6).

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).
