Teach the cursor visitor to walk all of the C and Objective-C

Create function, block, and template parameters in the context of the
translation unit. This is temporary for function and block parameters;
template parameters can just stay this way, since Templates aren't
DeclContexts. This gives us the nice property that everything created
in a record DC should have access in C++.

Add a test for clang_rt support on Darwin. With appropriate massaging, this

Speed up compilation by avoiding generating exceptional edges from
CallExprs as those edges help cause a n^2 explosion in the number of
destructor calls. Other consumers, such as static analysis, that
would like to have more a more complete CFG can select the inclusion
of those edges as CFG build time.
This also fixes up the two compilation users of CFGs to be tolerant of
having or not having those edges. All catch code is assumed be to
live if we didn't generate the exceptional edges for CallExprs.

A Decl->getName() is not unique. However, the debug info descriptors
are uniqued. The debug info descriptor describing record's context is
necessary to keep two Decl's descriptor unique if their name match.
There is more work to do to create descriptors for DeclContext.
As a temp. step use type's name in FwdDecl.
In objective-c++ land, a block pointer is another object pointer.
So, casting a generic object pointer ('id' or 'Class') to the
block pointer is allowed. Fixes radar 7562285.

Introduce a new, cursor-based traversal function that visits the
children of a given cursor, regardless of what kind of cursor it
is. This is a generalization of clang_loadDeclaration and
clang_loadTranslationUnit that will also extent to statements,

visitor over to an instance of this traversal function internally.

Initial cut at integrating compiler-rt (on Darwin) w/ clang build.
- compiler-rt should be checked out into $LLVM_SRC_ROOT/projects/compiler-rt.
- On Darwin, this will automatically build the runtime libraries clang needs
into $OBJROOT/lib/clang/<version>/darwin/...
- The mechanism can easily support other platforms, and can eventually support
multiple platforms once clang has some kind of configure process (for
specifying the desired targets).
