  if we know that 'len != 0' and know that 'i == 0' then we know that
  'i < len' must evaluate to true and cannot evaluate to false

 ^(expression) or ^(int arg1, float arg2)(expression)

All block literals now require a compound statement.

Sema::CheckReturnStackAddr(): Make sure we skip over implicit casts.
Added some more test cases...

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

"Here is a patch what replaces std::ostream with llvm::raw_ostream. This patch
covers the AST library, but ignores Analysis lib."

 - For investigating warnings in system headers / builtins.
 - Currently also enables the behavior that allows silent redefinition
   of types in system headers. Conceptually these are separate but I
   didn't feel it was worth two options (or changing LangOptions).

Give string literals const element typesin C++, and cope with the deprecated C++ conversion from a string literal to a pointer-to-non-const-character

 - Follow C99 behavior of using other operand type when one of
   operands is a null pointer constant.
 - Fix overenthusiastic devolving of any Objective-C types to id:
   o If either operand has an Objective-C object type then:
     - If both operands are interfaces and either operand can be
       assigned to the other, use that type as the composite type.
     - Otherwise, if either type is id, use id as the composite type.
     - Otherwise, warn about incompatible types and use id as the
       composite type.
 - Return handling of qualified idea to separate test following
   general pointer type checking.
   o Upgraded from old code to allow devolving to id (without warning,
     which matches GCC).

Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.

Add comments about C++ clause 3.3.2p4 that mentions that the condition declaration should be local to an if/switch/while/for statement.

enable background logging of files that clang encounters problems on.

Fix <rdar://problem/6210791> clang ObjC rewriter: @try / @catch block with no @finally does not call objc_exception_try_exit.

Need a couple tweaks to RewriteObjCTryStmt(). Need to deal with implicit finally clauses (to make sure objc_exception_try_exit is called). Also fixed a related bug where we need to generate an implicit @catch else clause (to again make sure objc_exception_try_exit is called).
