aa841c306d C++: Use virtual dispatch in DefaultTaintTracking 
This bit is only used by the compatibility code that sends flow into
parameters of functions without body.

ec9ef33486 C++: IR data flow through inheritance conversions 
This makes IR data flow behave more like AST data flow, and it makes IR
virtual dispatch work without further changes.

49008c9ff5 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`.

fb4dac597c C++: Minimal caching of the IR type system 
This was the minimal amount of predicates I could easily cache without
introducing extra cached stages. The predicates that are not cached
here, like `CppType::getTypeSize` and `getCanonicalLanguageType`, appear
to be cheap.

I've tested that this avoids recomputation of the IR type system by
running

    grep -c 'Starting to evaluate predicate CppType::CppType::getIRType_dispred'

on the evaluator log for `IRSanity.ql`. It drops from 4 to 1. The
pretty-printed DIL drops from 79,175 lines to 76,326 lines.
