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.

Zachary Snow 71e7e09092 verilog: Support module-scoped task/function calls 
This is primarily intended to enable the standard-permitted use of
module-scoped identifiers to refer to tasks and non-constant functions.
As a side-effect, this also adds support for the non-standard use of
module-scoped identifiers referring to constant functions, a feature
that is supported in some other tools, including Iverilog.

Jannis Harder efd5b86eb9 aiger: Add yosys-witness support 
Adds a new json based aiger map file and yosys-witness converters to us
this to convert between native and AIGER witness files.

Jannis Harder f041e36c6e smtbmc: Add native json based witness format + smt2 backend support 
This adds a native json based witness trace format. By having a common
format that includes everything we support, and providing a conversion
utility (yosys-witness) we no longer need to implement every format for
every tool that deals with witness traces, avoiding a quadratic
opportunity to introduce subtle bugs.

Included:

  * smt2: New yosys-smt2-witness info lines containing full hierarchical
    paths without lossy escaping.
  * yosys-smtbmc --dump-yw trace.yw: Dump results in the new format.
  * yosys-smtbmc --yw trace.yw: Read new format as constraints.
  * yosys-witness: New tool to convert witness formats.
    Currently this can only display traces in a human-readable-only
    format and do a passthrough read/write of the new format.
  * ywio.py: Small python lib for reading and writing the new format.
    Used by yosys-smtbmc and yosys-witness to avoid duplication.

Jannis Harder a2f9ebe43a memory_map: Add -formal option 
This maps memories for a global clock based formal verification flow.
This implies -keepdc, uses $ff cells for ROMs and sets hdlname
attributes.

Jannis Harder c0063288d6 Add the $anyinit cell and the formalff pass 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
use different backends simultaneously.
