types match. ExtWarn when user code is actually making use of this

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).

the sign bit doesn't have undefined behavior, but a signed left shift of a 1 bit
out of the sign bit still does. As promised to Howard :)
The suppression of the potential constant expression checking in system headers
is also removed, since the problem it was working around is gone.

This is a great warning, but it was observed that a ton of real world code violates
it all the time for (semi-)legitimate reasons. This warnings is fairly pedantic, which is good,
but not for everyone. For example, there is a fair amount of idiomatic code out there
that does "default: abort()", and similar idioms.

a typedef of std::pair. This slightly improves type-safety, but mostly
makes code using it clearer to read as well as making it possible to add
methods to the type.
Add such a method for efficiently single-step desugaring a split type.
Add a method to single-step desugaring a locally-unqualified type.
Implement both the SplitQualType and QualType methods in terms of that.
Also, fix a typo ("ObjCGLifetime").

This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

MAP_ERROR to be remapped to MAP_WARNING. These new APIs are being added to
allow the diagnostic mapping's "no Werror" bit to be set, and potentially
downgrade anything already mapped to be a warning.

Parsing of @implementations was based on modifying global state from
the parser; the logic for late parsing of methods was spread in multiple places
making it difficult to have a robust error recovery.
-it was difficult to ensure that we don't neglect parsing the lexed methods.
-it was difficult to setup the original objc container context for parsing the lexed methods
after completing ParseObjCAtImplementationDeclaration and returning to top level context.
Enhance parsing of @implementations by centralizing it in Parser::ParseObjCAtImplementationDeclaration().
ParseObjCAtImplementationDeclaration now returns only after an @implementation is fully parsed;
all the data and logic for late parsing of methods is now in one place.
This allows us to provide code-completion for late parsed methods with mis-matched braces.
