T.foo(1)
}

C++: IR data flow local virtual dispatch

This is just good enough to cause no performance regressions and pass
the virtual-dispatch tests we have for `security.TaintTracking`. In
particular, it fixes the tests for `UncontrolledProcessOperation.ql`
when enabling `DefaultTaintTracking.qll`.

C++/C#: Make AliasedUse access only non-local memory
...
The `AliasedUse` instruction is supposed to represent future uses of aliased memory after the function returns. Since local variables from that function are no longer allocated after the function returns, the `AliasedUse` instruction should access only the set of aliased locations that does not include locals from the current stack frame.

C++/C#: Add AliasedUse instruction to all functions
...
This new instruction is the dual of the existing `AliasedDefinition` instruction. Whereas that instruction defines the contents of aliased memory before the function was called, `AliasedUse` represents the potential use of all aliased memory after the function returns. This ensures that writes to aliased memory do not appear "dead", even if there are no further reads from aliased memory within the function itself.

C++: No CopyValue for immediately discarded exprs
...
Expressions like the `e` in `e;` or `e, e2`, whose result is immediately
discarded, should not get a synthetic `CopyValue`. This removes a lot of
redundancy from the IR.
To prevent these expressions from being confused with the expressions
from which they get their result, the predicate
`getInstructionConvertedResultExpression` now suppresses results for
expressions that don't produce their own result. This should fix the
mapping between expressions and IR data-flow nodes.
