5efc8ac1a4 Fix backwards flow through TaintTracking::FunctionModel
We only do this for taint models as there isn't any backwards flow
through data flow function models.

3906f2560d Adjust Stack Exposure test so it passes
A minor bug in our CFG means that we evaluate the base of a
SliceExpr before the bounds. Since the bounds may have side
effects, as in this case, it would be better to evaluate them first.
But in the short term I am just adjusting the test to make it work.

62155876c5 Fix flow to variable capture
The jump step to a `SsaCaptureVariable` should start at the last use
before it, rather than from the previous definition.

ac71f9cd8e Expected change in test output
These sources are now modeled using models-as-data, which (probably
correctly) uses the post-update node as the source. But the deprecated
QL models still exist, so we get two test results for each of these
calls.

203952fa47 Convert post-update logic to IR (part 2)
Note that we don't create post-update nodes for method receivers if the
call to the method is indirect, via a function variable. We could aim to
do this in future.

9068315f03 Fix IncorrectIntegerConversion for use-use flow
We were assuming that `sink` only had one successor, the TypeCastNode, but it
can now have an adjacent use as well.

b2a9cecd69 Fix Allocation Size Overflow for use-use flow
We have an operator expression like `x * 5`. We want to follow where the
value of the operator expression goes. We used to follow local flow from
an operand, but now there is flow from that operand to the next use of
the variable. The fix is to explicitly start local flow from the
operator expression.

There are also some expected edge changes due to use-use flow.
