Martin Povišer 62d6338688 quicklogic: Fix pp3 `dffs` test
Fix name confusion which was making the test look into the vendor's cell
blackbox rather than into the synthesis results.

Zachary Snow 4edb1a1921 sv: support assignments within expressions
- Add support for assignments within expressions, e.g., `x[y++] = z;` or
  `x = (y *= 2) - 1;`. The logic is handled entirely within the parser
  by injecting statements into the current procedural block.
- Add support for pre-increment/decrement statements, which are
  behaviorally equivalent to post-increment/decrement statements.
- Fix non-standard attribute position used for post-increment/decrement
  statements.

Charlotte ce245b5105 cxxrtl_backend: respect sync `$print` priority
We add a new flow graph node type, PRINT_SYNC, as they don't get handled
with regular CELL_EVALs.  We could probably move this grouping out of
the dump method.

Charlotte a1de898fcc fmt: merge fuzzers since we don't rely on BigInteger logic
This is per fmt's (effective) use, as it turns out, so we're not losing
any fidelity in the comparison.

Charlotte 3571bf2c2d fmt: fuzz, remove some unnecessary busywork
Removing some signed checks and logic where we've already guaranteed the
values to be positive.  Indeed, in these cases, if a negative value got
through (per my realisation in the signed fuzz harness), it would cause
an infinite loop due to flooring division.

Charlotte 2ae551c0af fmt: fuzz, fix (remove extraneous + incorrect fill)
"blk + chunks" is often an overrun, plus the fill is unnecessary; we

Charlotte 51d9b73107 fmt: tests completing again
We need to invoke "read_verilog" manually, since the default action on
input files is to defer processing.  Under such conditions, we never
simplify the AST, and initial $prints never execute.

Martin Povišer f8325f66b7 opt_expr: Fix 'signed X>=0' replacement for wide output ports
If the `$ge` cell we are replacing has wide output port, the upper bits
on the port should be driven to zero. That's not what a `$not` cell with
a single-bit input does. Instead opt for a `$logic_not` cell, which does
zero-pad its output.

Fixes #3867.

Martin Povišer 93988ef5df tests: Extend aigmap.ys with SAT comparison
Extend the aigmap.ys test with SAT-based comparison of the original
cells and their AIG implementations.

This tests both the usual cells and the single-bit Yosys gates.

Martin Povišer f0ae046c5a opt_share: Fix input confusion with ANDNOT, ORNOT gates
Distinguish between the A, B input ports of `$_ANDNOT_`, `$_ORNOT_`
gates when considering those for sharing. Unlike the input ports of the
other supported single-bit gates, those are not interchangeable.

Fixes #3848.

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.
