Prune unreachable paths in the Java dataflow library based on call context.
...
We now detect patterns like
f(bool cond){
if(cond)
then A
else B
and prune branches for calls like f(true) or f(false).
This pruning is done both in the local (bigstep) flow graph
as well as in the inter-procedural dataflow graph.

Add tests exhibiting false positives in the dataflow library, where call context is not used to prune branches.

C#/C++/Java: Unbreak partial data flow support
...
Partial data flow had a semantic merge conflict with this branch. The
problem is that partial data flow doesn't (and shouldn't) cause the
initial pruning steps to run, but the length-2 access paths depend on
the `consCand` information that comes from that initial pruning. The
solution is to restore the old `AccessPath` class, now called
`PartialAccessPath` for use only by partial data flow.
With this change, partial data flow will in some cases allow more field
flow than non-partial data flow.

Java: Accept test changes
...
Note: the results in `partial` have regressed and will need to be fixed
in a follow-up commit.
