aa35f24290 sv: auto add nosync to certain always_comb local vars 
If a local variable is always assigned before it is used, then adding
nosync prevents latches from being needlessly generated.

in the corresponding case in `simplify()`.

4cd2f03e36 preprocessor: do not destroy double slash escaped identifiers 
The preprocessor currently destroys double slash containing escaped
identifiers (for example \a//b ). This is due to next_token trying to
convert single line comments (//) into /* */ comments. This then leads
to an unintuitive error message like this:
ERROR: syntax error, unexpected '*'

This patch fixes the error by recognizing escaped identifiers and
returning them as single token. It also adds a testcase.

e833c6a418 verilog: use derived module info to elaborate cell connections 
- Attempt to lookup a derived module if it potentially contains a port
  connection with elaboration ambiguities
- Mark the cell if module has not yet been derived
- This can be extended to implement automatic hierarchical port
  connections in a future change
