14e49fb057 coolrunner2: Add an ANDTERM/XOR between chained FFs 
In some cases (e.g. the low bits of counters) the design might end up
with a flip-flop whose input is directly driven by another flip-flop.
This isn't possible in the Coolrunner-II architecture, so add a single
AND term and XOR in this case.

cfa3753b89 coolrunner2: Split multi-bit nets 
The PAR tool doesn't expect any "dangling" nets with no drivers nor
sinks. By splitting the nets, clean removes them.

6378e2cd46 First draft of Verilog parser support for specify blocks and parameters. 
The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST

2b9c75f8e3 This PR should be the base for discussion, do not merge it yet! 
It correctly detects reg/wire mix and incorrect use on blocking,nonblocking assignments within blocks and assign statements.

What it DOES'T do:
Detect registers connected to output ports of instances.

Where it FAILS:
memorty nonblocking assignments causes spurious (I assume??) errors on yosys-generated "_ADDR", "_DATA", "EN" signals.

You can test it with tests/simple/reg_wire_error.v (look inside for the comments to enable/disable specific lines)
