Jannis Harder dcc4d6e90b yosys-witness: Don't treat aiw x-bits as don't change 
While treating initialization only bits as don't change during later
cycles is correct, actual x-bits should be kept as x-bits.

POSIX test only allows "=" for string comparison.  Accepting "==" as
an alias is a bashism.  Even the bash manpage discourages its use.

Jannis Harder e36c71b5b7 Use clk2fflogic attr on cells to track original FF names in witnesses 
This makes clk2fflogic add an attr to $ff cells that carry the state of
the emulated async FF. The $ff output doesn't have any async updates
that happened in the current cycle, but the $ff input does, so the $ff
input corresponds to the async FF's output in the original design.

Hence this patch also makes the following changes to passes besides
clk2fflogic (but only for FFs with the clk2fflogic attr set):

  * opt_clean treats the input as a register name (instead of the
    output)

  * rename -witness ensures that the input has a public name

  * the formal backends (smt2, btor, aiger) will use the input's
    name for the initial state of the FF in witness files

  * when sim reads a yw witness that assigns an initial value to the
    input signal, the state update is redirected to the output

This ensures that yosys witness files for clk2fflogic designs have
useful and stable public signal names. It also makes it possible to
simulate a clk2fflogic witness on the original design (with some
limitations when the original design is already using $ff cells).

It might seem like setting the output of a clk2fflogic FF to update the
input's initial value might not work in general, but it works fine for
these reasons:

  * Witnesses for FFs are only present in the initial cycle, so we do
    not care about any later cycles.

  * The logic that clk2fflogic generates loops the output of the
    genreated FF back to the input, with muxes in between to apply any
    edge or level sensitive updates. So when there are no active updates
    in the current gclk cycle, there is a combinational path from the
    output back to the input.

  * The logic clk2fflogic generates makes sure that an edge sensitive
    update cannot be active in the first cycle (i.e. the past initial
    value is assumed to be whatever it needs to be to avoid an edge).

  * When a level sensitive update is active in the first gclk cycle, it
    is actively driving the output for the whole gclk cycle, so ignoring
    any witness initialization is the correct behavior.

CORRADI Quentin e7156c644d Standard compliance for tests/verilog/block_labels.ys 
genvar declaration cannot take an initial value when declared as a module_or_generate_item_declaration.
Correct this test so that it doesn't fail unexpectedly if Yosys aligns with the standard.

Jannis Harder ad2b04d63a sim: Fix cosimulation with nested modules having unconnected inputs 
When assigning values to input ports of nested modules in cosimulation,
sim needs to find the actual driver of the signal to perform the
assignment. The existing code didn't handle unconnected inputs in that
scenario.

Jannis Harder e6f3914800 smt2: Use smt bv offset for `$any*`'s smtoffset 
While not setting the smtoffset here was clearly a bug, I think using
`chunk.offset` only worked incidentally. The `smtoffset` is an offset
into the `smtname, smtid` pair (here `"", idcounter`) which corresponds
to the smt bitvector `stringf("%s#%d", get_id(module), idcounter)` which
contains all the chunks this loop is iterating over.

Thus using an incrementing `smtoffset` (like the `$ff`/`$dff` case above
already does) should be the correct fix.

Assign wires an smtoffset 
Wires weren't being assigned an smtoffset value so when generating a yosys witness trace it would also use an offset of 0.
Not sure if this has any other effects, but it fixes the bug I was having.
@jix could you take a look at this?
