Dag Lem a32d9b6c45 Fix test of memory vs. memory converted to registers 
The purpose of memtest02 in tests/simple/memory.v is to	test bit
select on both memory (mem1) and memory converted to registers (mem2).

After 7cfae2c52, mem1 was automatically converted to registers,
and the test no longer worked as intended. This is fixed by
adding (* nomem2reg *) to mem1.

Catherine 1236bb65b6 read_verilog: don't include empty `opt_sva_label` in span. 
Consider this SystemVerilog file:

    module top(...);
      input clk;
      input [7:0] data;
      input ack;

      always @(posedge clk)
        if (ack) begin
          assert(data != 8'h0a);
        end
    endmodule

Before this commit, the span for the assert was:

        if (ack) begin>
          assert(data != 8'h0a)<;

After this commit, the span for the assert is:

        if (ack) begin
          >assert(data != 8'h0a)<;

This helps editor integrations that only look at the beginning
of the span.

Jannis Harder 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" *)

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.
