Summary:
Currently cfg nodes are written into dot files in whatever order they
appear in a hash table. This seems unnecessarily sensitive, so this
diff sorts the nodes.

Run all clang tests with project-root at `infer/tests`. I need it because we'll start resolving symbolic links
soon and some tests would lead outside of project root which means we'd start seeing absolute paths in recorded tests.

Summary:
Create dummy functions representing the initializers of global variables. This
is so we can implement checks in the backend that can look at the initializer
expressions of global variables. We try not to create these dummy functions
when the initializer is not present, although for some reason we sometimes end
up with empty initializers.
Also add source file info to global variables in the backend (Pvar.re).

Rename symbols in test files so they are not duplicated and files can be analyzed together without affecting analysis results.
Fix some compilation errors, where files could be analyzed but would fail direct compilation.

Previously, we would translate `throw` with `return`. However, `throw` in
ObjC/C++ is often used to mean "abort". We now translate `throw` the same as
`exit` to prune these paths.

The extra dereference in stmtexpr was wrong. When a dereference is needed, we have a cast.

Summary:Local variable created by conditional operator translation is now declared in scope of whole
procedure. Semantically there is no difference, hopefuly backend will not complain about this
change. Also, nullifying that variable is deferred to preanalysis instead of calling it manually

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.

Instead of using location of init_stmt, use location of variable when translating initialization.
Most of the time it change anything with some exceptions:
// example1 - C/C++/objC
int x = // now: assignment happens in this line
3; // past: assignment happens in this line
// example2: valid in C++11 only
struct X {
int x = 0; // now: one assignment here
int y = 2; // now: one assigmnent here
X() = default; // before: 2 assignments in this line

Summary:public This also required a refactoring of InitListExpr.
The idea is that ImplicitValueInitExpr can stand for initialising a whole struct,
so we translating as a list of zero expressions, according to the struct's fields,
which is then paired with a list of field expressions, such that one get a list of
assignment instructions.

Summary:public
Improved/simplified framework for fronend checkers.
Now we have a unique hook from cTrans to run checkers on statements and a unique
hook from cFrontent to run checkers on declarations.
So now when adding a checker we don't have to modify cTrans/cFrontend.
Moreover made more sistematic the way checkers are invoked. This simplify the definition
of checkers and the way we use them.
Code is now simpler.

in the preanalysis. This diff adds a builtin getter that gets called if we are going to skip the function. That
means, if there was a getter written by the developers we still use that one rather than the builtin.
