Removed the VlTriggerVec type, and refactored to use an unpacked array
of 64-bit words instead. This means the trigger vector and its
operations are now the same as for any other unpacked array. The few
special functions required for operating on a trigger vector are now
generated in V3SchedTrigger as regular AstCFunc if needed.
No functional change intended, performance should be the same.
The AstIf nodes conditional on events being triggered used to be created
in V3Clock. Now it is in V3Sched*, in order to avoid having to pass
AstActive in CFunc or MTask bodies. No functional change intended, some
improved optimization due to simplifying timing triggers that were
previously missed, also fixes what seems like a bug in the original
timing commit code.
Continuing the idea of decoupling the implementations of the various algorithms.
The main points:
-Move the former "processDomain" stuff, dealing with assigning combinational logic into the relevant sensitivity domains into V3OrderProcessDomains.cpp
-Move the parallel code construction in V3OrderParallel.cpp (Could combine this with some parts of V3Partition - those not called from V3Partition::finalize - but that's not for this patch).
-Move the serial code construction into V3OrderSerial.cpp
-Factored the very small common code between the parallel and serial code construction (processMoveOneLogic) into V3OrderCFuncEmitter.cpp
Move OrderBuildVisitor into V3OrderGraphBuilder.cpp (and rename to
V3OrderGraphBuilder). Move ProcessMoveBuildGraph to
V3OrderMoveGraphBuilder.cpp (and rename to V3OrderGraphBuilder).
This patch is pure code movement/rename, no refactoring at all.
