Richard Trieu Add template type diffing to Clang. This feature will provide a better
comparison between two templated types when they both appear in a diagnostic.
Type elision will remove indentical template arguments, which can be disabled
with -fno-elide-type.  Cyan highlighting is applied to the differing types.

For more formatting, -fdiagnostic-show-template-tree will output the template
type as an indented text tree, with differences appearing inline. Template
tree works with or without type elision.

Timur Iskhodzhanov Add a few (currently failing) tests for the PR13207 (template manglin…
…g in the presence of back references).

I've added an extra FileCheck pass for that with an extra "CURRENT" prefix.
I've carefully chosed the CURRENT/CORRECT prefixes so they
a) are self-descriptive
b) have the same length so the mangling between the current and the correct version is obvious

Feel free to ask me to change the prefixes if you know a better alternative.

Jordan Rose [analyzer] Add a test that we are, in fact, doing a DFS on the Explod…
…edGraph.

Previously:
...the comment said DFS...
...the WorkList being instantiated said BFS...
...and the implementation was actually DFS...
...due to an unintentional change in 2010...
...and everything kept working anyway.

This fixes our std::deque implementation of BFS, but switches back to a
SmallVector-based implementation of DFS.

We should probably still investigate the ramifications of DFS vs. BFS,
especially for large functions (and especially when we hit our block path
limit), since this might completely change our memory use. It can also mask
some bugs and reveal others depending on when we halt analysis. But at least
we will not have this kind of little mistake creep in again.

@chandlerc chandlerc Switch Clang to use the new common LLVM CMake infrastructure for adding
lit testsuites. This sinks all management of the aggregate lit runs into
the LLVM CMake files, making Clang only responsible for declaring its
own testsuite. In the process we fix numerous "bugs" where the proper
method of invoking lit has changed over time, and the old system
encoded several broken artifacts of this in ABIs and compatibility
tests.

It also switches to 'check-clang' for the canonical name of the test
suite, although 'clang-test' remains as an alias.

The situation when Clang is being built in standalone mode is little
changed. It replicates just enough of the lit setup to cope with the
oddities of being run outside of an LLVM build.

Since extracting comments isn't free, a new code completion option is

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

@akyrtzi akyrtzi [PCH] Make sure that all newly introduced visible decls in a DeclContext
coming from an AST file are registered for serialization.

A static data member instantiation of in a chained PCH could be missed
when serializing decls; the result was that when emitting the visible decls
map of its DeclContext, we would use a DeclID that was not actually emitted,
leading to crashes or hangs.

Fix this by making sure such decls are always registered for serialization.
Also introduce extra sanity checks to make sure we don't register new
declarations or types after we have serialized the types/decls block.

Jordan Rose [analyzer] Add a new abstraction over all types of calls: CallEvent
This is intended to replace CallOrObjCMessage, and is eventually intended to be
used for anything that cares more about /what/ is being called than /how/ it's
being called. For example, inlining destructors should be the same as inlining
blocks, and checking __attribute__((nonnull)) should apply to the allocator
calls generated by operator new.

Jordan Rose [analyzer] Convert RetainCountChecker to use CallEvent as much as pos…
…sible.

This ended allowing quite a bit of cleanup, and some minor changes.

- CallEvent makes it easy to use hasNonZeroCallbackArg more aggressively, which
  we check in order to avoid false positives with callbacks that might release
  the object.
- In order to support this for functions which consume their arguments, there
  are two new ArgEffects: DecRefAndStopTracking and DecRefMsgAndStopTracking.
  These act just like StopTracking, except that if the object only had a
  return count of +1 it's now considered released instead (so we still get
  use-after-free messages).
- On the plus side, we no longer have to special-case
  +[NSObject performSelector:withObject:afterDelay:] and friends.
- The use of IdentifierInfos in the method summary cache is now hidden; only
  the ObjCInterfaceDecl gets passed around most of the time.
- Since we cache all "simple" summaries and check every function call, there is
  no real benefit to having NULL stand in for default summaries anymore.
- Whitespace, unused methods, etc.

Even more simplification to come when we get check::postCall and can unify all
these other post* checks.

Jordan Rose [analyzer] Convert CallAndMessageChecker and ObjCSelfInitChecker to C…
…allEvent.

Both of these got uglier rather than cleaner because we don't have preCall and
postCall yet; properly wrapping a CallExpr in a CallEvent requires doing a bit
of deconstruction on the callee. Even when we have preCall and postCall we may
want to expose the current CallEvent to pre/postStmt<CallExpr>.

Jordan Rose [analyzer] Move the last bits of CallOrObjCMessage over to CallEvent.
This involved refactoring some common pointer-escapes code onto CallEvent,
then having MallocChecker use those callbacks for whether or not to consider
a pointer's /ownership/ as escaping. This still needs to be pinned down, and
probably we want to make the new argumentsMayEscape() function a little more
discerning (content invalidation vs. ownership/metadata invalidation), but
this is a good improvement.

As a bonus, also remove CallOrObjCMessage from the source completely.

Jordan Rose [analyzer] Begin replacing ObjCMessage with ObjCMethodCall and friends.
Previously, the CallEvent subclass ObjCMessageInvocation was just a wrapper
around the existing ObjCMessage abstraction (over message sends and property

ObjCMessageSend and ObjCPropertyAccess.

In addition to removing yet another wrapper object, this should make it easy
to add a ObjCSubscriptAccess call event soon.

Jordan Rose [analyzer] Finish replacing ObjCMessage with ObjCMethodDecl and friends.

Jordan Rose In blocks, only pretend that enum constants have enum type if necessary.
In C, enum constants have the type of the enum's underlying integer type,
rather than the type of the enum. (This is not true in C++.) Thus, when a
block's return type is inferred from an enum constant, it is incompatible
with expressions that return the enum type.

In r158899, I told block returns to pretend that enum constants have enum
type, like in C++. Doug Gregor pointed out that this can break existing code.

Now, we don't check the types of return statements until the end of the block.
This lets us go back and add implicit casts in blocks with mixed enum
constants and enum-typed expressions.

Jordan Rose [analyzer] For now, don't inline non-static member overloaded operators.
Our current inlining support (specifically RegionStore::enterStackFrame)
doesn't know that calls to overloaded operators may be calls to non-static
member functions, and that in these cases the first argument should be
treated as 'this'. This caused incorrect results and sometimes crashes.

The long-term fix will be to rewrite RegionStore::enterStackFrame to use
CallEvent and its subclasses, but for now we can just disable these
problematic calls by classifying them under a new CallEvent,
CXXMemberOperatorCall.
