Fix change detection at time 0 (#5864)

function, instead of the 'initial' blocks function. Fixes #5499

Set trigger vector in whole words (#5857) 
Having many triggers still hits a bottleneck in LLVM leading to long
compile times.

Instead of setting triggers bit-wise, set them as a whole 64-bit word
when possible. This improves C++ compile times by ~4x on some large
designs and has minor run-time performance benefit.

Do not use function locals in SenExprBuilder (#5822) 
Function locals are not safe here because we might need to split up
the generated function. V3Localize can fix them later if safe.

Split V3Order into further part and decouple various components (#4953) 
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

Geza Lore 4c0edd2efb Improve --prof-exec infrastructure and report 
Again --prof-exec have bit-rotted a little with all the recent changes
to the structure of the generated code. This patch contains a few
improvements:
- Repalce the eval/evl_loop begin/end events with generic
  section_push/section_pop events, that can be arbitrarily sprinkled
  into the generate code (so long as they are matched correctly) to
  measure various sections. The report then contains a nested profile
  of the sections, and the VCD trace shows the section names.
- Better handling of exec graphs
- Clearer overall statistics

Geza Lore 0e769d42a1 Optimize trigger evaluation 
Pack the elements of VlTriggerVec as dense bits (instead of a 1 byte
bool per bit), and check whether they are set on a word granularity.
This effectively transforms conditions of the form `if (trig.at(0) |
trig.at(2) | trig.at(64))` into `if (trig.word(0) & 0x5 | trig.word(1) &
0x1)`. This improves OpenTitan ST by about 1%, worth more on some other
designs.
