C++: Generate IR side effects for smart pointer indirections
...
When inserting side effect instructions for argument indirections, we now insert side effects for smart pointers as we would for raw pointers. The address operand of the side effect instruction is the smart pointer object, which is a bit odd. However, I'd like to think through the design of a more principled solution before doing additional work.
A few new tests are added to the existing IR tests. In addition, the IR tests now `#include` some of the shared STL headers. I've disabled IR dumps for functions from those headers, since they only get in the way of the test cases we intended.
