98d6f3cada C++: Unify partial def and def-by-ref 
This removes a lot of flow steps, but it all seems to be flow that was
present twice: both exiting a `PartialDefNode` and a
`DefinitionByReferenceNode`. All `DefinitionByReferenceNode`s are now
`PartialDefNode`s.

5370e7d693 C++: Remove TThisVar 
There's no need to model `this` as a variable because it's never
reassigned.

861964337c C++: Undo autoformat of FlowVar.qll 
The formatting changes were good, but were tangled in with other
changes, making it hard to review this file.

d378da33e8 C++ IR: Fix performance of large array value init 
There were two problems here.

1. The inline predicates `isInitialized` and `isValueInitialized` on
   `ArrayAggregateLiteral` caused their callers to materialize every
   `int` that was a valid index into the array. This was slow on huge
   value-initialized arrays.
2. The `isInitialized` predicate was used in the `TInstructionTag` IPA
   type, creating a numbered tuple for each integer in it. This seemed
   to be entirely unnecessary since the `TranslatedElement`s using those
   tags were already indexed appropriately.

de9b936d76 QLDoc tidy up Declaration.qll 
Mostly just adding backticks in QLDoc comments.  I'm trying out the edit-in-github workflow @jbj showed me, which seems like it will be a quicker way to do minor changes like these.
