C++: Add flow through arrays
...
This works by adding data-flow edges to skip over array expressions when
reading from arrays. On the post-update side, there was already code to
skip over array expressions when storing to arrays. That happens in
`valueToUpdate` in `AddressFlow.qll`, which needed just a small tweak to
support assignments with non-field expressions at the top-level LHS,
like `*a = ...` or `a[0] = ...`.
The new code in `AddressFlow.qll` is copy-pasted from `EscapesTree.qll`,
and there is already a note in these files saying that they share a lot
of code and must be maintained in sync.

C++: Field flow through ConstructorFieldInit
...
This allows a member initializer list to be seen as a sequence of field
assignments. For example, the constructor
C() : a(taint()) { }
now has data flow similar to
C() { this.a = taint(); }

C++: Improved ConstructorCall field flow
...
This commit changes C++ `ConstructorCall` to behave like
`new`-expressions in Java: they are both `ExprNode`s and
`PostUpdateNodes`, and there's a "pre-update node" (here called
`PreConstructorCallNode`) to play the role of the qualifier argument
when calling a constructor.
