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.

PR12196: The module hash strings are not actually hashing the compiler version
string; the entire version string is being included in the hash.  Depending on
the module cache directory name, that can lead to failures where the path
names become too long.  As a temporary workaround, just remove the version
string from the hash.

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.

If you're using git-svn, the clang and llvm repository will typically
map to a different revision.

Before we had:
clang version 3.1 (trunk 152167 trunk 152162)

After this change:
clang version 3.1 (trunk 152167) (llvm/trunk 152162)

So it's self-descriptive with an extra parens group. Which is more
compatible with version string parsers is probably debatable, but this
style was requested.

This submission improves Clang sema handling by using Clang tablegen
to generate common boilerplate code. As a start, it implements AttributeList
enumerator generation and case statements for AttributeList::getKind.

A new field "SemaHandler" is introduced in Attr.td and by default set to 1
as most of attributes in Attr.td have semantic checking in Sema. For a small
number of attributes that don't appear in Sema, the value is set to 0.

Also there are a small number of attributes that only appear in Sema but not
in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

The declarations of the operators no longer matched.
The definitions in ASTContext.h had 'throw()' removed,
but it was still present in Attr.h.

Somehow the buildbots missed this. clang merely warns about
a missing 'throw()' specification and suggested a Fix-It adding
it back, but gcc 4.5 is not so forgiving and gives an error.

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.

This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator.  We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

NSNumber, and boolean literals.  This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.

My apologies for the large patch.  It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.

Docs are forthcoming to document the implementation and behavior of these features.
