65f4ef712e C++: accept false positive tests after merge
The IR false positives are due to the same path length limit as the AST
false positives on the same line.

5f0d283212 Merge remote-tracking branch 'upstream/master' into dataflow-indirect-args
The conflicts came from how `this` is now a parameter but not a
`Parameter` on `master`.

1b1095ee75 C++: Post-update flow through &, *, +, ...
Flow from a definition by reference of a field into its object was
working inconsistently and in a very syntax-dependent way. For a
function `f` receiving a reference, `f(a->x)` could propagate data back
to `a` via the _reverse read_ mechanism in the shared data-flow library,
but for a function `g` receiving a pointer, `g(&a->x)` would not work.
And `f((*a).x)` would not work either.

In all cases, the issue was that the shared data-flow library propagates
data backwards between `PostUpdateNode`s only, but there is no
`PostUpdateNode` for `a->x` in `g(&a->x)`. This pull request inserts
such post-update nodes where appropriate and links them to their
neighbors. In this exapmle, flow back from the output parameter of `g`
passes first to the `PostUpdateNode` of `&`, then to the (new)
`PostUpdateNode` of `a->x`, and finally, as a _reverse read_ with the
appropriate field projection, to `a`.
