from the frontend when the location is invalid and the SourceManager null.
Instead of keeping the SourceManager object in DiagnosticRenderer, propagate it
to the calls accordingly (as reference when it is expected to not be null, or pointer
when it may be null).
This effectively makes DiagnosticRenderer not tied to a specific SourceManager,
removing a hack from TextDiagnosticPrinter.

Per Greg Clayton:
libclang.dylib is trying to be smart and load itself at a valid address
to be able to load faster which would work for 32 bit systems,
bit won't make any difference on 64 bit systems.
It should either pick a better 64 bit address, or just let itself be loaded at zero.

code-completion related strings specific to a translation unit (ASTContext and related data)
CodeCompletionAllocator does such limited caching, by caching the name assigned
to a DeclContext*, but that is not the appropriate place since that object has
a lifetime that can extend beyond that of an ASTContext.
Introduce CodeCompletionTUInfo which will be always tied to a translation unit
to do this kind of caching and move the caching of CodeCompletionAllocator into this
object, and propagate it to all the places where it will be needed.
The plan is to extend the caching where appropriate, using CodeCompletionTUInfo,
to avoid re-calculating code-completion strings.

The ability to run over multiple translation units with different command

transformations across translation unit boundaries.

reference is going to message the setter, the getter, or both.
Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.
[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.
[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.
The general idea has the seal of approval by John.

Previously, only diagnostics thrown by the cc1 process were
actually honoring the diagnostic options given on the command line,
like -Werror.
Reuse the existing code in Frontend currently used for cc1,
adjusting it to not interpret -Wl, linker flags as warnings.
Also fix a faulty test exposed by this change.
It wasn't actually testing anything, and was giving this warning:
clang-3: warning: argument unused during compilation: '-verify'
Which -Werror didn't turn into an error because it was output
by the driver, not the cc1 process, and diagnostic options
weren't parsed by the driver. And you couldn't see the warning
when running the test suite.
Fixes PR12181.

To link with -static -lclang, linker tries to seek not libclang.so, clang.dll nor libclang.dll.a, but libclang.a. USEDLIBS should have correct dependencies for -static.
(In contrast, USEDLIBS=libclang.so might be enough w/o -static)
FYI, cygwin build (in buildbot) is using -static, due to avoiding weirdness of extremely slower startup lag of clang.exe.

Basically the current design is:
-for an implementation method, show as overridden the interface method.
This is not useful, and is inconsistent with the C++ side
-for an interface method, show as overridden the protocols methods (this is desirable)
and the methods from the categories; methods from categories are not useful
since they are considered the same method (same USR).
-If there is a protocol method or category method reported, it does not check the
super class for overridden methods. This is really problematic since
overridden methods from super class is what we want to give back.
Change clang_getOverriddenCursors to show as overridden any method in the class's
base class, its protocols, or its categories' protocols, that has the same
selector and is of the same kind (class or instance).
If no such method exists, the search continues to the class's superclass,
its protocols, and its categories, and so on. A method from an Objective-C
implementation is considered to override the same methods as its
corresponding method in the interface.

analysis to make the AST representation testable. They are represented by a
new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic
properties, including full CodeGen support, are achieved for free by this
representation.
UserDefinedLiterals can never be dependent, so no custom instantiation
behavior is required. They are mangled as if they were direct calls to the
underlying literal operator. This matches g++'s apparent behavior (but not its
actual mangling, which is broken for literal-operator-ids).
User-defined *string* literals are now fully-operational, but the semantic
analysis is quite hacky and needs more work. No other forms of user-defined
literal are created yet, but the AST support for them is present.
This patch committed after midnight because we had already hit the quota for
new kinds of literal yesterday.

compiler errors or not.
-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.
[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.
The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.
This breaks the static analysis of new expressions. I've filed PR12014 to track this.

This option was added in r129614 and doesn't have any use case that I'm aware
of. It's possible that external tools are using these names - and if that's
the case we can certainly reassess the functionality, but for now it lets us
shave out a few unneeded bits from clang.
Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool.
This removes the actual diagnostic name strings from clang entirely.
