Summary:
There were overly complex and different ways of identifying C++/objC languages. Simplify and unify them.
How I came up with naming - there are two languages C and C++. You can apply "Objective-" extention to both of them.
We usually need to differentiate C and C++ (different AST) and whether it's extended (checks specific to ObjC)

This helps avoid some unintended reports where the actual is known to point to

Summary:
Use Itanium mangling for C++ functions/methods instead of raw type name. This is a step towards removing expensive `ti_raw` field from `type_info`.
For virtual methods, use mangled name of the method from base class in order for dynamic dispatch to work.

Summary:
Class names fragile, easy to break and they introduce another level of indirection.
Since C++ translation doesn't need names, pass decl pointers everywhere.
Doing otherwise will most likely result in assert false.
Handling of class names in objc translation is more involving and it's left
for now. Later, objc can use same mechanism as C++.

Summary:
When clang instantiates template function with argument pack, it will
give the same name to all parameters coming from the pack. To avoid
name collisions, always add index of argument's position to mangled part
of the variable.
Seemingly unrelated changes are to make existing tests pass (don't use
simple variable name where it matters)

Summary:
Now that array types record only static - and therefore constant -
lengths, Sil typ and exp no longer need to be mutually recursive.
This diff:
- splits the recursion in the type definitions of typ and exp,
- splits the recursion in the comparison and pretty-printing
functions,
- and then refactors typ into a separate module.

Summary:
Reimplement command line options in preparation for uniformly passing
options from the top-level infer driver that invokes a build command
through the build system to the descendant infer processes.
All command line options of all executables are collected into Config,
and declared using a new CommandLineOption module that supports
maintining backward compatibility with the current command line
interface. Very few values representing command line options are
mutable now, as they are set once during parsing but are constant
thereafter. All ordering dependencies are contained within the
implementation of Config, and the implementation of Config is careful to
avoid unintended interactions and ordering dependencies between options.

Summary:public
When a conditional is the last instruction, there will be a join node leading directly to the exit node.
Some instructions, such as nullification of dead variables, and abstraction, are added to the control flow graph automatically. But, join nodes cannot contain instructions. So when a procedure ends with a conditional, there might be no place to store these instructions.
This diff adds one extra node between the join and the exit node in that situation.

I have seen enough comments in this space by people during code review to switch on the analyses the compiler can already do. This diff is an automated renaming of unused identifiers to _, with a few additional changes made when reading the diff of the results for things that stood out as particularly strange. This base-lines all of the existing warnings. I'm not sure this is a good idea, since it might be better for those familiar with each part of the code to look at these warnings and use them as pointers to suspicious code.
