C++: Fix failed tests

Added a new `StaticLocalVariable` class, which made several other pieces of the original change a bit cleaner. Fixed test failures due to a mistake in the original `CFG.qll` change. Added a test case for static local variables with constructors. Removed the `Uninitialized` instruction from the initialization of a static local, because all objects with static storage duration are zero-initialized at startup. Fixed expectations for `SignAnalysis.ql` to reflect that a bad result is now fixed.
