Jeff Wang 249876b614 support using previously declared types/localparams/params in package
(parameters in systemverilog packages can't actually be overridden, so
allowing parameters in addition to localparams doesn't actually add any
new functionality, but it's useful to be able to use the parameter
keyword also)

Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)

Jeff Wang 16ea4ea61a partial rebase of PeterCrozier's enum work onto current master
I tried to keep only the enum-related changes, and minimize the diff. (The
original commit also had a lot of work done to get typedefs working, but yosys
has diverged quite a bit since the 2018-03-09 commit, with a new typedef
implementation.) I did not include the import related changes either.

Original commit:
"Initial implementation of enum, typedef, import.  Still a WIP."

whitequark e97e33d00d kernel: require \B_SIGNED=0 on $shl, $sshl, $shr, $sshr.
Before this commit, these cells would accept any \B_SIGNED and in
case of \B_SIGNED=1, would still treat the \B input as unsigned.

Also fix the Verilog frontend to never emit such constructs.

Udi Finkelstein 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)
