fix bug introduced by not taking all of PeterCrozier's changes in 16ea4ea6
...
The if(str == node->str) is in fact necessary (otherwise causes generate
for in Multiplier_2D in tests/simple/multiplier.v to fail with error
message "Right hand side of 3rd expression of generate for-loop is not
constant!"). Note: in PeterCrozier's implementation, the break only
breaks out of the switch-case, not the outer for loop.

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."
