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.

This is not strictly behaviour preserving, but I believe the parts I've removed or simplified weren't intended to do what they were doing.

1e6c983d62 C++: Use getASTVariable in DefaultTaintTracking 
This library is not yet used in a query or test, so it broke silently
when `VariableAddressInstruction.getVariable` was removed.

56cbd0c152 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.
