79e05a195d verilog: Bufnorm cell backend and frontend support 
This makes the Verilog backend handle the $connect and $input_port
cells. This represents the undirected $connect cell using the `tran`
primitive, so we also extend the frontend to support this.

3d2bb1db17 verilog_parser: replace manual AST node allocation with typed midrule actions 
Use Bison's typed midrule actions to construct AST_FCALL nodes
with std::unique_ptr, replacing manual 'new' and extra->ast_stack
management. This improves type safety, ensures proper ownership, and
eliminates potential memory leaks.

There are some leftovers, but this is an easy regex-based approach that removes most of them.

9a6f25fb73 verilog_parser: Use unique_ptr<> to store the attribute list. 
We can get rid of the new / delete statements and free_attr() and we
don't need to manage the memory manually.

c30fd46ea3 Fix handling of cases that look like sva labels again. 
Commit c8e0ac0 introduces a regression on handling case exprs that look
like sva labels.  After some debugging, we shouldn't push the identifier
ast node to the ast_stack, otherwise, we will get the following
assertion failure:

d10190606c verilog: Lower required bison version to 3.6 
We're currently on version 3.6 of bison at Google, and Yosys
still correctly builds with it. This should better reflect
the actual requirements rather than an overly restrictive
check. If features from 3.8 are required it seems like bumping
would be appropriate.
