Remove some warnings (#2448)

* Fix unreachable code warning by changing match order

Simulation Statements did not previously extend IsDeclaration, but now
they do so their match blocks need to be above IsDeclaration.

* Handle MemoryNoInit case in RtlilEmitter

* Remove use of deprecated logToFile

* Fix uses of LegalizeClocksTransform

Replaced all uses of LegalizeClocksTransform with
LegalizeClocksAndAsyncResetsTransform.

* Remove use of CircuitForm in ZeroWidth
