f9e69984ff Set vlSymsp in modules at construction time. 
This ensures it's available from very early on. No functional change.

b1b5b5dfe2 Improve run-time profiling 
The --prof-threads option has been split into two independent options:
1. --prof-exec, for collecting verilator_gantt and other execution
related profiling data, and
2. --prof-pgo, for collecting data needed for PGO

The implementation of execution profiling is extricated from
VlThreadPool and is now a separate class VlExecutionProfiler. This means
--prof-exec can now be used for single-threaded models (though it does
not measure a lot of things just yet). For consistency VerilatedProfiler
is renamed VlPgoProfiler. Both VlExecutionProfiler and VlPgoProfiler are
in verilated_profiler.{h/cpp}, but can be used completely independently.

Also re-worked the execution profile format so it now only emits events
without holding onto any temporaries. This is in preparation for some
future optimizations that would be hindered by the introduction of function
locals via AstText.

Also removed the Barrier event. Clearing the profile buffers is not
notably more expensive as the profiling records are trivially
destructible.

bab8462789 Rebuild run-time library if generated makefile changes 
The generated makefile contains compiler options that are passed when
building the run-time library, so re-build if it changes.

5b9806ae6d Improve V3Combine 
- Always use a fast function to replace a slow one if available
- Iterate to fixed point (i.e.: if combining made more functions
identical, combine those too). This will be more useful in the future.
- Use only single, const traversal

4b79d23d00 Replace SenTreeSet with generic collection 
Introduce VNRef that can be used to wrap AstNode keys in STL
collections, resulting in equality comparisons rather than identity
comparisons. This can then replace the SenTreeSet data-structure.
