C++: insert Chi nodes in the IR successor relation
...
This commit adds Chi nodes to the successor relation and accounts for
them in the CFG, but does not add them to the SSA data graph. Chi nodes
are inserted for partial writes to any VirtualVariable, regardless of
whether the partial write reaches any uses.

C++: Accept test changes for IR
...
This test was failing due to a semantic merge conflict between #509 ,
which added `UninitializedInstruction`, and #517 , which added new test
code that would get `UninitializedInstruction`s in it after merging with #509 .

C++: Detect non-allocating placement new
...
This adds a `NewOrNewArrayExpr.getPlacementPointer` predicate and uses
it in `Alloc.qll` to detect when a `new`-expression is not an
allocation.
User-defined replacements for `operator new` may not be allocations
either, but the code continues to assume that they are. It's possible
that we want to change this assumption in the future or leave it up to
individual queries to decide on which side to err. It's hard to
statically tell whether `operator new` has been overloaded in a
particular file because it can be overloaded by a definition that is not
in scope but is only linked together with that file.

C++: Add Uninitialized instruction for list-initialized variables
...
This commit inserts an `Uninitialized` instruction to "initialize" a local variable when that variable is initialized with an initializer list. This ensures that there is always a definition of the whole variable before any read or write to part of that variable.
This change appears in a different form in @rdmarsh2's Chi node PR, but I needed to refactor the initialization code anyway to handle ConditionDeclExpr.
