[PATCH] Implement CapturedStmt AST

  A few minor comments, but the code that's here looks fine. However, it doesn't belong in the Clang tree until it does *something*. Let's get a basic captured statement parsing (with no capture yet, of course!) and building this AST.

More detail, please. What does it mean to capture a statement into a function? What source code would result in a captured statement?

Because we only have 'this' and by-reference captures, there is no need for a CopyExpr. Please remove it; it can be reintroduced when it's needed (and it won't be a part of the stored Capture, since that doesn't work with children()).
