      Remove vtables from the Stmt hierarchy; this was pretty easy as · bd066789
      John McCall authored 
      there were only three virtual methods of any significance.

The primary way to grab child iterators now is with
  Stmt::child_range children();
  Stmt::const_child_range children() const;
where a child_range is just a std::pair of iterators suitable for
being llvm::tie'd to some locals.  I've left the old child_begin()
and child_end() accessors in place, but it's probably a substantial
penalty to grab the iterators individually now, since the
switch-based dispatch is kindof inherently slower than vtable
dispatch.  Grabbing them together is probably a slight win over the
status quo, although of course we could've achieved that with vtables, too.

I also reclassified SwitchCase (correctly) as an abstract Stmt
class, which (as the first such class that wasn't an Expr subclass)
required some fiddling in a few places.

There are somewhat gross metaprogramming hooks in place to ensure
that new statements/expressions continue to implement
getSourceRange() and children().  I had to work around a recent clang
bug;  dgregor actually fixed it already, but I didn't want to
introduce a selfhosting dependency on ToT.

      static analyzer: Further reduce the analyzer's memory usage when analyzing sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes.

The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain
practically no difference between the predecessor and successor nodes.  For example, if
the state is different between a predecessor and a node, the node is left in.  Only for
the 'environment' component of the state do we not care if the ExplodedNodes are different.
This paves the way for future optimizations where we can reclaim the environment objects.

      [analyzer] Fix a false positive of the 'self' initialization checker. · dd03d8dd
      Argyrios Kyrtzidis authored 
      A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:

   if (!(self = [super init]))
     return nil;
   if (!(self = _commonInit(self)))
     return nil;

It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.

Fixes rdar://8937441 & http://llvm.org/PR9094
