2963dc1cb1 C++: Include phi read nodes in SSA. 
There's a small fix to the mapping from 'global def -> use'.

Finally, this commit also accepts a test failure related to new missing
types for phi nodes. The fix for that is in the next commit.

4e16bb65e3 C++: Accept test changes. Because we now allocate _three_ indirect nodes 
for a value of type `void*` (i.e., `p`, `*p` and `**p`) we need to decide
on a type for the `**p` value. We will do this in the next commit.

bdce24735c 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.

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`.

1d56407c72 C++: Pull some of library-tests/dataflow/dataflow-tests into clang.cpp 
g++ doesn't support this code:

    sorry, unimplemented: non-trivial designated initializers not supported
       twoIntFields sSwapped = { .m2 = source(), .m1 = 0 };

so we need to build it in clang mode.
