function call operator (to the lambda class). This allows us to IRgen
calls to simple (non-capturing) lambdas, e.g.,
[](int i, int j) -> int { return i + j; }(1, 2)
Eli will be providing test cases as he brings up more IRgen.

We were passing a decl to the consumer after all pending deserializations were finished
but this was not enough; due to processing by the consumer we may end up into yet another
deserialization process but the way FinishedDeserializing() was setup we would not ensure
that everything was fully deserialized before returning to the consumer.
Separate ASTReader::FinishedDeserializing() into two semantic actions.
The first is ensuring that a deserialization process ends up will fully deserialized decls/types even
if the process is started by the consumer.
The second is pushing "interesting" decls to the consumer; we make sure that we don't re-enter this
section recursively be checking a variable.

difference in the qual type. This is a workaround for the fact that
the type isn't artificial but the this decl is, however, we don't
have any way of representing it in the current metadata. For now,
however, just don't cache the full type.
Fixes rdar://10831526 and probably a couple of others.

empty union. This still rejects anonymous member structs or unions which only
contain such empty class types, pending standard wording defining exactly what
an empty class type is.

calls to Decl::getASTContext() by Decl's methods will find the TranslationUnitDecl

This was from way-back-when (r82583) when Clang's C++ support wasn't prime-time
yet. Production quality C++ was tested experimentally from r100119 and turned
on by default in r141063.

- Complete the lambda class when we finish the lambda expression
(previously, it was left in the "being completed" state)
- Actually return the LambdaExpr object and bind to the resulting
temporary when needed.
- Detect when cleanups are needed while capturing a variable into a
lambda (e.g., due to default arguments in the copy constructor), and
make sure those cleanups apply for the whole of the lambda
expression.

which allows values to escape through unknown calls.
Assumes all calls but the malloc family are unknown.
Also, catch a use-after-free when a pointer is passed to a
function after a call to free (previously, you had to explicitly
dereference the pointer value).

optimistic.
TODO: actually implement the pessimistic version of the checker. Ex: it
needs to assume that any function that takes a pointer might free it.
The optimistic version relies on annotations to tell us which functions
can free the pointer.

only add 'const' for variables captured by copy in potentially
evaluated expressions of non-mutable lambdas. (The "by copy" part was
missing).
