Summary: The prune nodes where translated as `prune (expr = false)` and `prune ( expr != false)`. This case is a bit tricky to deconstruct in HIL. This diff translates the prune instructions as just `prune !expr` for the true branch and `prune expr` for the false branch.

appear in a hash table. This seems unnecessarily sensitive, so this

Dealing with symbolic links in project root is tricky. To avoid it, always normalize all paths to sources with `realpath`.
Changes to tests are expected - infer started to resolve symbolic links which screws up with our testing mechanism.

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).

The extra dereference in stmtexpr was wrong. When a dereference is needed, we have a cast.
This was causing one dereference too many, and creating wrong results.

It turns out that C-like structs in C++ may have methods generated by clang (constructors for example).
If struct has a method, it needs to have Sil.Class type - make all CXXRecordDecls Sil.Class types by default.

Update facebook-clang-plugins. Changes:
- [major] new clang
- dump class template instantiations
- change naming for qual names of anonymous structs
Changes are due to:
1. Different setter properties are exported for defaults (more correct). Fix the test that was wrong
2. New unary operator type
3. Naming for qual names changed

New qual_name exporting logic in facebook-clang-plugins handles anonymous
classes in much better way. This allows us to simplify name generation for
classes that don't rely on a type of the object (which could be wrong for
methods from superclasses).

Summary: public anonymous types have file:line in its name.
Since file is relative path, type name can have '/' in its name.
This is very fragile since we might create file wiht typename in its name (for example for methods).
Replacing '/' with '_' should make frontend more resilient to failure.
Translation of anonymous structs is still pretty fragile (due to relative path in its name),
but at least it doesn't crash frontend

Summary: public
C++ assignment operation result is lvalue, while in C it was rvalue.
This leads to different AST produced by clang for then same code!
Use language information from clang (`-x` flag) to distinguish these cases.
More specifically, let's look at following code:
int r;
int f = (r = 3);
// type of (r = 3) expression:
// C/objC -> int rvalue
// C++/objC++ -> int lvalue
Existing code did extra dereference because it was rvalue in C and there was no cast afterwards
in C++ there will be extra LValueToRvalue cast when neccesary so we don't have to do extra dereference manually
Reference:
http://en.cppreference.com/w/c/language/value_category (search for 'assignment and compound assignment operators')
NOTE: AST output doesn't change when something is hidden behind `extern "C"`, so we should use global language information

Summary: @public
This removes the old way of finding variable declarations to create sil variables and replaces it with
a a new way based on the map from pointers to declarations.
Basically, every variable dereference contains a pointer to the variable declaration, with that we can
build the corresponding sil variable.
