Optimize primitive runtime functions
...
These were a victim of recent refactor but are actually important
(#4733 ). It also helps in debug builds not to use -O0 memcpy/memset.

Fix erroneous implicit conversions of VlWide ( #7642 )
...
Change WDataInP/WDataOutP to be opaque handles types instead of aliases
to raw pointers. This subsequently eliminates needing an implicit cast
operator in VlWide, which is replaced with implicit constructors of
WDataInP/WDataOutP that can create a handle from a VlWide. This
eliminates some unsafe conversions that the previous implicit cast
operator unintentionally enabled (e.g. #7618 ). It also eliminates
having to insert ".data()" in various places int he generated code, which
simplifies internals (the only place ".data()" should be needed is in
calls to variadic functions where the expected type of the argument is
not WDataInP/WDataOutP).
The handles otherwise behave like pointers, implementing the minimal
amount of operators required to code the runtime. The handle is still
only a single pointer, and will be passed in registers as before, so
this patch should be performance neutral.
As part of this removed WData, which used to be an alias for EData.
All uses are now either EData*, WDataInP, WDataOutP, or VlWide directly.

Internals: Replace VlTriggerVec with unpacked array ( #6616 )
...
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.
