Internals: Use a V3Graph for the hierarchical plan (#6545) 
I stared this because the emitted makefiles for hierarchical verilation
were non-deterministic (iterating unordered_map indexed by pointers).
Then I realized that the V3HierPlan is just a dependency graph encoded
in a slightly idiosyncratic way. We do have a data structure to use for
that instead.

With that the output should always be deterministic + have nicer dumps.

Remove/fix/signoff uncontroversial code coverage holes. Also added a
couple TODOs that should be investigated at some point

Internals: Optimize temporary memory allocations (#6517) 
This patch gets rid of over 80% of temporary dynamic memory allocations
(when a malloced node is immediately freed with no other malloc in
between). It also gets rid of over 20% of all calls to malloc.

It's worth ~3% average verilation speed up with tcmalloc, and more
without tcmalloc.

Internals: Enable EmitV to output formatted code to std::ostream (#6239) 
Introduce V3OutStream as a V3OutFormatter that writes to a stream
instead of a file. This can be used to emit formatted code fragments
e.g. in debug prints and graph dumps.

'virtual' is redundant when 'override' is present, so keep only

Emit model implementation as loose methods. (#3006) 
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.
