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.

9f0892159e flatten, techmap: don't canonicalize tpl driven bits via sigmap. 
For connection `assign a = b;`, `sigmap(a)` returns `b`. This is
exactly the opposite of the desired canonicalization for driven bits.
Consider the following code:

    module foo(inout a, b);
      assign a = b;
    endmodule
    module bar(output c);
      foo f(c, 1'b0);
    endmodule

Before this commit, the inout ports would be swapped after flattening
(and cause a crash while attempting to drive a constant value).

This issue was introduced in 9f772eb9.

Fixes #2183.

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.

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.
