10d5d358d2 Ignore $scopeinfo in write_aiger 
While SBY's aiger flow already removes non-assertion driving logic,
there are some uses of write_aiger outside of SBY that could end up with
$scopeinfo cells, so we explicitly ignore them.

The write_btor backend works differently and due to the way it
recursively visits cells, it would never reach isolated cells like
$scopeinfo.

0470cbb00d hierarchy: Without a known top module, derive all deferred modules 
This fixes hierarchy when used with cell libraries that were loaded with
-defer and also makes more of the hierarchy visible to the auto-top
heuristic.

verific: Fixes incorrect aldff inference in verific importer 
The following SV module at HEAD imported with verific,

```systemverilog
    module my_module(
      input logic [4:0] a,
      input logic clk,
      input logic enable,
      output logic [4:0] z
    );

    reg [4:0] pipeline_register;
    always @(posedge clk) begin
      pipeline_register <= enable ? a : pipeline_register;
    end
    assign z = pipeline_register;

    endmodule : my_module

```

results in the following output verilog

```systemverilog
/* Generated by 0.36 */

(* top =  1  *)
(* hdlname = "my_module" *)
(* src = "/tmp/temp_directory_zTwd0l/my_input.v:2.12-2.21" *)

  wire [4:0] _0_;

endmodule
```

Yosys is incorrectly infering aldffs due to an incorrect conversion
of logical 1 and 0 SigBits.

My PR unifies the conversion of Verific::Net objects into SigBits using
Yosys' internal representation of special signals like 0,1,x,z. After
my PR these signals are correctly converted into DFFs.

6c4902313b chformal: Support $check cells and add chformal -lower 
This adds support for `$check` cells in chformal and adds a `-lower`
mode which converts `$check` cells into `$assert` etc. cells with a
`$print` cell to output the `$check` message.

331ac5285f tests: Run async2sync before sat and/or sim to handle $check cells 
Right now neither `sat` nor `sim` have support for the `$check` cell.
For formal verification it is a good idea to always run either
async2sync or clk2fflogic which will (in a future commit) lower `$check`
to `$assert`, etc.

While `sim` should eventually support `$check` directly, using
`async2sync` is ok for the current tests that use `sim`, so this commit
also runs `async2sync` before running sim on designs containing
assertions.

2baa578d94 Remove too fragile smtlib2_module test 
This compares the write_smt2 output pretty much verbatim, which contains
auto generated private names and fixes an arbitrary ordering. The tested
functionality is also covered by SBY tests which actually interpret the
write_smt2 output using an SMT solver and thus are much more robust, so
we can safely remove this test.
