clang's -Wuninitialized-experimental warning.
While these don't look like real bugs, clang's
-Wuninitialized-experimental analysis is stricter
than GCC's, and these fixes have the benefit
of being general nice cleanups.

For example: 

class A{ 
public:
  A& operator=(const A& that) {
      if (this != &that) {
          this->A::~A();
          this->A::A(that);  // <=== explicit constructor call.
      }
      return *this;
  }
};

More work will be needed to support an explicit call to a template constructor.

- Move MiscNameMangler member functions to MangleContext
- Remove GlobalDecl dependency from MangleContext
- Make MangleContext abstract and move Itanium/Microsoft functionality
  to their own classes/files
- Implement ASTContext::createMangleContext and have CodeGen use it

delete the block we began emitting into if it had no predecessors.  We never
want to do this, because there are several valid cases during statement
emission where an existing block has no known predecessors but will acquire
some later.  The case in my test case doesn't inherently fall into this 
category, because we could safely emit the case-range code before the statement
body, but there are examples with labels that can't be fallen into 
that would also demonstrate this bug.
