With this change, the clang-on-clang test result is now

Expected Passes    : 224
Unexpected Failures: 37

Which means that we can compile over 80% of clang with clang! :)

DependentScopeDeclRefExpr support storing templateids.  Unite the common   
code paths between ActOnDeclarationNameExpr and ActOnTemplateIdExpr.

This gets us to a point where we don't need to store function templates in
the AST using TemplateNames, which is critical to ripping out OverloadedFunction.

Also resolves a few FIXMEs.

make sure that this variable is destroyed when we exit the switch

We always need to emit the base expression of a member expression, even when the member decl refers to an enum. Thanks to Eli for pointing this out!

  - Outside the "if", to ensure that we destroy the condition variable
    at the end of the "if" statement rather than at the end of the
    block containing the "if" statement.
  - Inside the "then" and "else" branches, so that we emit then- or
    else-local cleanups at the end of the corresponding block when the
    block is not a compound statement.

To make adding these new cleanup scopes easier (and since
switch/do/while will all need the same treatment), added the
CleanupScope RAII object to introduce a new cleanup scope and make
sure it gets cleaned up.

static member constants. No significant visible difference at the moment
because it conservatively assumes the base has side effects. I'm planning to
use this for CodeGen.

It is common for vtables to contain pointers to functions that have either incomplete return types or incomplete argument types.

Handle this by returning the llvm::OpaqueType for those cases, which CodeGenModule::GetOrCreateLLVMFunction knows about, and treats as being an "incomplete function".

rather than burying it in a CXXConditionDeclExpr (that occassionally
hides behind implicit conversions). Similar changes for
switch, while, and do-while will follow, then the removal of
CXXConditionDeclExpr. This commit is the canary.

After performing a bounds check in ArrayBoundChecker, record the fact that a bounds check succeeded by transitioning the ExplodedGraph.

llvm-svn: 89712

along the way.  Important changes:

1) To generate a sink node, use GenerateSink(); GenerateNode() is for
generating regular transitions.  This makes the API clearer and also
allows us to use the 'bool' option to GenerateNode() for a different
purpose.

2) GenerateNode() now automatically adds the generated node to the
destination ExplodedNodeSet (autotransition) unless the client
specifies otherwise with a bool flag.  Several checkers did not call
'addTransition()' after calling 'GenerateNode()', causing the
simulation path to be prematurely culled when a non-fail stop bug was
encountered.

3) Add variants of GenerateNode()/GenerateSink() that take neither a
Stmt* or a GRState*; most callers of GenerateNode() just pass in the
same Stmt* as provided when the CheckerContext object is created; we
can just use that the majority of the time.  This cleanup also allows
us to potentially coelesce the APIs for evaluating branches and
end-of-paths (which currently directly use builders).

4) addTransition() no longer needs to be called except for a few
cases.  We now have a variant of addTransition() that takes a
GRState*; this allows one to propagate the updated state without
caring about generating a new node explicitly.  This nicely cleaned up
a bunch of cases that called autoTransition() with a bunch of
conditional logic surround the call (that common logic has now been
swallowed up by addTransition() itself).
