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.
Add V3SchedUtil.cpp that contains common small utility functions.
Add V3SchedTrigger.cpp that contains functionality building the trigger
mechanism code.
No functional change, just code movement. Prep for some further work.
