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`.

dd322be238 C++: Remove noise from argHasPostUpdate check 
This consistency check seems to have value for AST data flow, but I've
disabled it on the IR for now.

This commit also includes two unrelated changes that seem to fix a
semantic merge conflict.
