b6038f3caa C++: Remove best-bound logic from test

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.

d03a4f86e5 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.

6e61b1dcd0 C++: Fix up after merge from master 
The one interesting piece that needed to be fixed up was the type of an `Indirect[Read|Write]SideEffect` operand/result. If the parameter type is a pointer or reference to an incomplete type, we need to set the type of the side effect memory access to `Unknown`, because we don't model incomplete types in the IR type system.

I also added minimal support for `__assume` (generated as a `NoOp`), because lack of `__assume` support got in the way of debugging the other issue above.

two false negatives in the test cases from #2088.

01a3a037bc C++: Make complex_numbers/expr.ql less brittle 
This test used `getAQlClass`, which caused it to break when new classes
were added anywhere in the libraries. That's now avoided by switching to
`getCanonicalQLClass`. It turns out that `getCanonicalQLClass` didn't
support arithmetic expressions on complex numbers, so that support had
to be added.

2eed38e2d4 C++: Accept slight CFG regression in static init 
Hopefully it does not make a difference in practice whether
uninstantiated template functions are considered to have control flow
through initializers of their static variables.
